Description
Technical Field
The invention relates to a power cable tray storage device.
Background
Power cables are carriers of power transmission. According to different purposes, the power cable can be roughly divided into a bare wire and a cored wire, wherein the bare wire is mainly used for overhead transmission and the cored wire is mainly used for underground power transmission. With the development of modern city power transmission, underground power transmission has become a main means of city power transmission at present. Accordingly, more and more core-spun yarns are used. The cored wire is laid underground, and therefore, sufficient insulation performance must be ensured, which requires a relatively thick insulation layer, and thus the cored wire is generally much thicker than a bare wire.
Currently, power cables are typically wrapped around power cable trays for packaging, shipping, and storage. The power cable tray generally includes two circular plates coaxially spaced apart from each other, and the circular plates are fixed to each other by a coaxially disposed cylinder. Thus, the two circular plates and the cylinder form a roller, the inner walls of the two circular plates and the outer wall of the cylinder form a circular groove, namely the roller groove, and the power cable is wound on the periphery of the cylinder, namely in the circular groove.
Since the cored wires are generally copper-cored, and the bare wires are generally alloy and have high density, even a single power cable tray is light by hundreds of jin and heavy by tons, so that higher requirements are put on the packaging, transportation and storage of the power cables, especially higher requirements on storage. The requirements in the storage regulations of electrical equipment require that the power cable coil rack must be placed horizontally and strictly vertically when being stored, and the power cable coil rack is strictly stacked up and down on the premise of no interval supporting device. The transverse placement means that the axis of the power cable tray (namely, the roller) is transversely placed. The advantage of transversely placing is when hoisting the electric power cable plate rail with fork truck or crane, only need in the drum interpolation dress a bracing piece, with the crane or fork truck to the both ends of bracing piece upwards the application of force can, consequently can not hinder the electric power cable, it is very convenient. However, the disadvantage of the transverse placement is also obvious because the power cable tray is in the shape of a round roller, and after the power cable tray is transversely placed on the ground, the power cable tray is easy to roll under force, so that the power cable tray must be reliably fixed by using an auxiliary device. The strict vertical placement is to avoid inserting or scraping the outer insulating skin of the power cable when the power cable tray frame is hoisted, and the strict vertical stacking is also to avoid the upper and lower power cable tray frames from pressing the outer insulating skin of the power cable.
The number of electric power laying projects required to be performed is enormous, whether bare or cored, so that a power company warehouse must store a large number of electric power cable trays. Because there is no special storage device for storing power cable tray racks, power companies place various types of power cable tray racks on the ground of the warehouse in sequence, so that although the storage problem is solved, each power cable tray rack occupies a ground area, which results in a large amount of warehouse. Contrary to the power cable tray, other power devices such as transformers and compensation capacitors have rectangular wooden packing boxes which can be stacked up and down, so that too much warehouse space is not needed, and the utilization rate of the warehouse which is simply used for storing the power cable tray is low, so that the warehouse management and maintenance cost is high.
Disclosure of Invention
The invention aims to solve the technical problem of providing the storage device of the power cable tray frame, which has a reasonable structure, can be quickly assembled when in use, can realize the vertical stacking when the power cable tray frame is transversely placed, is firm to place, is simple to take and place, can be conveniently disassembled and stored when not in use, and occupies small space.
In order to solve the technical problem, the storage device for the power cable tray frame is characterized in that: including base and two hinges of setting in the base both sides, the hinge includes that the upper end passes through the articulated support arm together of hinge, the rigid coupling has the semi-ring between the hinge both ends, the support arm lower extreme clamps four bights at the base through clamping the piece, the eminence such as support arm sets firmly corresponds the xarm that sets up, be equipped with the upper bracket that is supported by the xarm between two hinges, the upper bracket passes through the retaining member and is in the same place with the xarm locking, the base middle part is equipped with the base hole that clamps the electric power cable plate rail frame, the ability splendid attire of upper bracket is downthehole at the base, the upper bracket middle part is equipped with the.
The electric power cable tray rack storage device can be quickly assembled when used through the assembled support structure, can be stacked up and down when the electric power cable tray rack is transversely placed, is firm to place and simple to take and place, and can be conveniently disassembled to be stored when not used, and the occupied space is small.
The assembled support structure mainly comprises a base and two hinged supports arranged on the base, wherein the two hinged supports are respectively arranged above the left half part and the right half part of the base, so that the base and the two hinged supports form a combined frame. The combined rack comprises a base, two foot rests arranged on the base, and a cavity which is formed by the base and two hinge brackets and is surrounded by the base and the two hinge brackets, wherein the cavity is used for storing a power cable tray frame. For convenience of description, the side or direction of the cavity is referred to as the inside or inner portion of the rack, the outer side of the rack is referred to as the outside or outer portion, the directions of the two sides of the base in which the hinge bracket is located in the horizontal plane are referred to as the left and right, and the remaining two directions are referred to as the front and rear.
The hinge frame comprises two support arms hinged together through a hinge shaft, the hinge shaft is positioned at the upper ends of the support arms, and the two ends of the hinge shaft are also connected with the half rings, so that a crane or a travelling crane can play a role in hoisting the hinge frame by drawing the half rings, and the hinge frame is very convenient. The lower ends of the support arms are clamped with the four corners of the base through the clamping parts, so that the lower ends of the two support arms of the same hinge frame are respectively clamped on the two corners at the same side of the base. That is to say, the upper ends of the two support arms of the hinge are hinged at one point through the hinge shaft, and the lower ends of the two support arms are respectively clamped on two corners far away from the base, so that the hinge and the base part on the same side are clamped to form a triangular support, which is referred to as a "triangular support" here for short, and the triangular support has extremely strong structural stability according to the mechanics common knowledge, so that the structural stability of the electric power cable tray storage device in the front-back direction is ensured, and the electric power cable tray storage device cannot deform or rock back-forth.
Each support arm is fixedly provided with a cross arm, and the heights of the cross arms on the support arms are the same, namely the cross arms are arranged at the same height. Thus, even when the two support arms are swung open to form a tripod with the base, the four cross arms on the four support arms are arranged at the same height.
The power cable tray storage device further comprises an upper frame, wherein the upper frame is positioned in the combined overhead cavity and supported by the four cross arms of the hinge frame. A locking part is arranged between the side part of the upper frame and the cross arm matched with the support, and the locking part has the main function of locking the upper frame and the cross arm together, namely locking the upper frame between the two hinged frames. Thus, the lower ends of the two hinged brackets are fixedly clamped at four corners of the base, and the middle upper parts of the two hinged brackets are fixedly locked together through the upper bracket and the locking part, so that a 'laminated bracket' which has a more stable structure than a combined bracket and is supported by the two hinged brackets and has an upper-lower two-layer structure of the upper bracket and the base is formed. The laminated frame has extremely strong structural stability in the front-rear direction under the support of the tripod, and cannot rock in the front-rear direction after being subjected to the action of external force. Because two triangular supports link together through upper bracket and base, consequently two triangular supports support each other in the left and right sides orientation, have also guaranteed the structural stability of range upon range of frame in the left and right sides orientation, have avoided rocking in the left and right sides orientation after the atress.
The base is provided with a base hole in the middle, and the base hole is arranged corresponding to the power cable tray frame, that is, the base hole is wider than the power cable tray frame, but shorter than the diameter of the power cable tray frame. When the power cable tray frame is hoisted by a crane or is forked by a forklift to be arranged above the base hole and falls down, the lowest end of the power cable tray frame can enter the base hole, but the periphery of the power cable tray frame can be clamped on the side wall of the base hole. Therefore, the base not only plays a role in storing the power cable tray frame, but also clamps the power cable tray frame through the base hole and plays a role in fixing the power cable tray frame, so that the operation of storing and fixing the power cable tray frame is integrated into one step, and the operation is simpler.
Similarly, the middle part of the upper frame is also provided with a hole which is called an upper frame hole, and the main function of the upper frame hole is also to store the power cable tray frame. In theory, the power cable tray frame with the same size as the base hole can be clamped in the upper frame hole, and the power cable tray frame smaller than the power cable tray frame clamped in the base hole can also be clamped in the upper frame hole. However, since the stacked rack is triangular in height and the upper rack is disposed at the middle or middle upper portion of the arm, the power cable tray in the upper rack hole is smaller than the power cable tray in the base hole in order to ensure the stability of the stacked rack for storing the power cable tray.
As can be understood from the mechanical analysis, since the entire stack is triangular, the center of gravity of the stack body is located at the center of the lower middle portion of the stack. After the power cable tray frame is clamped in the base hole, the dead weight of the power cable tray frame is far larger than that of the stacking frame, so that the gravity center of the power cable tray frame clamped in the base hole is basically the gravity center of the power cable tray frame. After the power cable tray frame is also hoisted in the upper rack hole, the weight of the power cable tray frame in the upper rack hole is smaller than that of the power cable tray frame in the base hole, so that the weight of the power cable tray frame in the upper rack hole is smaller than that of the power cable tray frame in the base hole. Therefore, after the power cable tray frames are clamped in the base hole and the upper frame hole, the total gravity center of the stacking frame and the two power cable tray frames is slightly higher than the center of the power cable tray frames in the base hole, but is still positioned at the lower part of the stacking frame, so that the structural stability and the noninterference of the upper power cable tray frame and the lower power cable tray frame when the power cable tray frames are transversely placed and stacked up and down are ensured.
When using, need earlier this electric power cable tray rack strorage device fast assembly, its operating procedure is: firstly, hoisting a hinged support by a crane or a forklift or manpower through the half rings, and then clamping the lower end of the support arm onto the base through a clamping piece, thereby completing the assembly work of the combined frame; then the upper frame is hoisted to the cross arm by a crane or a forklift or manpower and is locked and fixed by the locking piece, thus the assembly work of the laminated frame is completed, and the operation is simple and quick.
When the electric cable tray frame needs to be stored, the supporting rods are inserted into the cylinders of the electric cable tray frame, then the two ends of the supporting rods are forked by a forklift and are sent into the cavities above the base holes or the racking holes, when the electric cable tray frame reaches the positions above the base holes or the racking holes, the forklift is controlled to slowly put down the electric cable tray frame and withdraw, the storage work of the electric cable tray frame can be completed, and the operation is very simple.
When the stored electric cable tray frame needs to be taken, the supporting rods only need to be inserted into the cylinders of the electric cable tray frame, then the two ends of the supporting rods are forked by the forklift and lifted, so that the electric cable tray frame can be lifted away from the base holes or the upper frame holes, and finally the forklift is driven to drag the electric cable tray frame out of the cavity, so that the operation is very simple.
When the hinge frame needs to be disassembled after being taken, the assembling process is opposite to the assembling process, namely, the locking piece is unlocked firstly, the upper frame is taken down, then the hinge frame is lifted away from the base by a crane or a forklift or manually, and the two support arms of the hinge frame are folded and then stored, so that the storage space can be saved. In this electric power cable tray rack strorage device, the whole upper ledge of base hole ability splendid attire just can reduce this electric power cable tray rack strorage device's occupation space greatly like this after dismantling, provides more spaces for depositing other power equipment.
As the improvement, the cable tray rack further comprises a top frame supported by four cross arms above the upper frame, the top frame comprises a top frame, a top frame hole for clamping a cable tray rack is formed in the middle of the top frame, a cross arm which extends outwards and is in press fit with the cross arms is fixedly arranged on the upper portion of the top frame, the cross arm is locked with the cross arms through locking pieces, and the top frame can be contained in the upper frame hole.
After the top frame is placed on the four corresponding cross arms above the upper frame, the power cable tray frame can be clamped in the top frame hole of the top frame, so that the number of the power cable tray frame storage device for stacking the power cable tray frames up and down is increased, and the effect of saving the storage space is better. Because the top frame of the top frame can be completely placed in the upper frame hole, the size of the top frame hole is inevitably smaller than that of the upper frame hole, and the weight of the power cable tray frame placed in the top frame hole is also inevitably smaller than that of the power cable tray frame placed in the upper frame hole. The total gravity center of the whole power cable tray storage device and the contained power cable tray will rise, but the power cable tray in the top frame hole is lightest, so that the lifting effect of the total gravity center is also minimum, and the stability of the storage of the three power cable trays by the power cable tray storage device cannot be influenced.
As an improvement, the outer end of the hinge shaft is hinged with a side lever through a horizontal hinge shaft, the side of the base is hinged with a connecting rod capable of swinging horizontally outwards, and the tail end of the side lever is connected with the lower end of the connecting rod through a connecting piece.
After the outer end of the hinge shaft is hinged with the side rod through the horizontal hinge shaft, the side rod can swing around the horizontal hinge shaft. When the side rod is in a disassembly state, the side rod and the two support arms can be folded together, and the storage space is saved. When the side rod is in a use state, the side rod can swing outwards around the horizontal hinge shaft, the effect of an auxiliary supporting tripod can be achieved, and the effect of preventing the whole electric power cable tray rack storage device from inclining in the left and right directions is enhanced. The side of the base is provided with a connecting rod corresponding to the side rod, one end of the connecting rod is hinged with the middle of the side of the base, and the connecting rod can swing in the horizontal plane. Because the length of the side rod is slightly longer than that of the support arm, when the connecting rod swings away from the base and is vertical to the side of the base, the lower end of the side rod just corresponds to the tail end of the connecting rod. A connecting piece is arranged between the tail end of the connecting rod and the lower end of the side rod, and the lower end of the side rod is fixedly connected with the tail end of the connecting rod through the connecting piece. Thus, the side bars, the connecting rods and the tripod constitute a new tripod, which is called a "right-angled tripod" for convenience of description. The connecting rod and the tripod respectively form two right-angle sides of the right-angle tripod, and the side rod forms an inclined side of the right-angle tripod. Likewise, the right-angled tripod is also a triangular structure, and the structural stability of the right-angled tripod is undoubted, so that the right-angled tripod structurally ensures the vertical state of the tripod, and the inclination of the whole power cable tray storage device to the left or the right is fundamentally avoided.
As an implementation mode, the clamping piece comprises four bottom holes arranged at four corners of the base, the lower end of the support arm is fixedly provided with an insertion block which is inserted and matched with the bottom holes, and the lower part of the insertion block is in a wedge shape with a narrow lower part and a wide upper part.
The bottom hole on the base is matched with the inserting block at the lower end of the supporting arm in an inserting mode, so that the bottom hole and the inserting block have mutual limiting effects in any direction in the horizontal plane, the included angle of the two supporting arms is fixed after the hinge frame is subjected to the gravity of the power cable reel frame, and the structural stability of the tripod is guaranteed. Although the bottom hole and the insertion block have no mutual limiting effect in the vertical direction, after the power cable tray frame is clamped, the weight of the power cable tray frame is enough to enable the insertion block to be firmly inserted into the bottom hole. The lower part of the insert block is set into a wedge shape with a narrow lower end and a wide middle part, so that when the tripod is assembled, people can insert the insert block into the bottom hole quickly, and the assembling time is shortened.
As an implementation mode, the locking piece comprises locking holes arranged on the cross arm and the upper frame and locking bolts inserted into the locking holes.
Adopt locking hole and locking bolt as the retaining member, can insert locking bolt in locking hole between them fast when locking, realize quick locking, help realizing fast assembly.
As an improvement, the upper part of the cross arm is in a wedge shape with a narrower upper end and a wider middle part, the middle part and the lower part of the cross arm are in equal width, four corners of the upper frame are cross rods extending towards the outer cross arm, the cross section of each cross rod is in an n shape with a downward opening, and the opening of each cross rod is matched with the cross arm clamping sleeve.
The cross rod is designed into the n-shaped structure with the downward opening, so that when the upper frame is placed on the cross rod, the cross rod can be assembled and matched with the cross rod in a buckling mode, and the side wall of the cross rod of the n-shaped structure can play a role in wrapping the cross rod after buckling, so that the two sides of the cross rod can be limited, and the reliability of connection between the cross rod and the cross rod is improved. The upper part of the cross arm is set into a wedge shape with a narrow upper end and a wide lower end, so that the guide effect of the cross rod when the cross arm is buckled on the cross arm can be achieved, the buckling success rate is improved, and the quick assembly is realized.
As a further improvement, four corners of the base hole are provided with cross rod cavities matched with the cross rod, and convex blocks matched with the cross rod opening support are fixedly arranged in the cross rod cavities.
The base is provided with the cross rod cavity matched with the cross rod, so that the base hole can completely accommodate the whole upper frame, and the base and the upper frame can be overlapped to form a flat plate in a disassembly state, thereby effectively saving the occupied area. The lug matched with the opening of the cross rod is arranged at the bottom of the cross rod cavity, so that when the upper frame is placed into the base hole, the whole upper frame can be supported by the lug through the cross rod, and therefore when the base is moved, the upper frame can be moved together with the upper frame, and the lifting device is very convenient.
In conclusion, the storage device for the power cable tray rack with the structure is reasonable in structure, can be quickly assembled when in use, can realize the vertical stacking when the power cable tray rack is transversely placed, is firm in placement and simple to take and place, can be conveniently disassembled and stored when not in use, occupies a small space, and is particularly suitable for being used when a large number of power cable tray racks are quickly stored in a warehouse with a limited space.

Therefore, the base not only plays a role in storing the power cable tray frame, but also clamps the power cable tray frame through the base hole and plays a role in fixing the power cable tray frame, so that the operation of storing and fixing the power cable tray frame is integrated into one step, and the operation is simpler.
Similarly, the middle part of the upper frame is also provided with a hole which is called an upper frame hole, and the main function of the upper frame hole is also to store the power cable tray frame. In theory, the power cable tray frame with the same size as the base hole can be clamped in the upper frame hole, and the power cable tray frame smaller than the power cable tray frame clamped in the base hole can also be clamped in the upper frame hole. However, since the stacked rack is triangular in height and the upper rack is disposed at the middle or middle upper portion of the arm, the power cable tray in the upper rack hole is smaller than the power cable tray in the base hole in order to ensure the stability of the stacked rack for storing the power cable tray.
As can be understood from the mechanical analysis, since the entire stack is triangular, the center of gravity of the stack body is located at the center of the lower middle portion of the stack. After the power cable tray frame is clamped in the base hole, the dead weight of the power cable tray frame is far larger than that of the stacking frame, so that the gravity center of the power cable tray frame clamped in the base hole is basically the gravity center of the power cable tray frame. After the power cable tray frame is also hoisted in the upper rack hole, the weight of the power cable tray frame in the upper rack hole is smaller than that of the power cable tray frame in the base hole, so that the weight of the power cable tray frame in the upper rack hole is smaller than that of the power cable tray frame in the base hole. Therefore, after the power cable tray frames are clamped in the base hole and the upper frame hole, the total gravity center of the stacking frame and the two power cable tray frames is slightly higher than the center of the power cable tray frames in the base hole, but is still positioned at the lower part of the stacking frame, so that the structural stability and the noninterference of the upper power cable tray frame and the lower power cable tray frame when the power cable tray frames are transversely placed and stacked up and down are ensured.
When using, need earlier this electric power cable tray rack strorage device fast assembly, its operating procedure is: firstly, hoisting a hinged support by a crane or a forklift or manpower through the half rings, and then clamping the lower end of the support arm onto the base through a clamping piece, thereby completing the assembly work of the combined frame; then the upper frame is hoisted to the cross arm by a crane or a forklift or manpower and is locked and fixed by the locking piece, thus the assembly work of the laminated frame is completed, and the operation is simple and quick.
When the electric cable tray frame needs to be stored, the supporting rods are inserted into the cylinders of the electric cable tray frame, then the two ends of the supporting rods are forked by a forklift and are sent into the cavities above the base holes or the racking holes, when the electric cable tray frame reaches the positions above the base holes or the racking holes, the forklift is controlled to slowly put down the electric cable tray frame and withdraw, the storage work of the electric cable tray frame can be completed, and the operation is very simple.
When the stored electric cable tray frame needs to be taken, the supporting rods only need to be inserted into the cylinders of the electric cable tray frame, then the two ends of the supporting rods are forked by the forklift and lifted, so that the electric cable tray frame can be lifted away from the base holes or the upper frame holes, and finally the forklift is driven to drag the electric cable tray frame out of the cavity, so that the operation is very simple.
When the hinge frame needs to be disassembled after being taken, the assembling process is opposite to the assembling process, namely, the locking piece is unlocked firstly, the upper frame is taken down, then the hinge frame is lifted away from the base by a crane or a forklift or manually, and the two support arms of the hinge frame are folded and then stored, so that the storage space can be saved. In this electric power cable tray rack strorage device, the whole upper ledge of base hole ability splendid attire just can reduce this electric power cable tray rack strorage device's occupation space greatly like this after dismantling, provides more spaces for depositing other power equipment.
This electric power cable tray rack strorage device still includes the roof-rack 10 that is supported by four xarm 5 above putting on the shelf 6, and roof-rack 10 includes top frame 11, and top frame 11 middle part is equipped with the roof-rack hole 12 that clamps the electric power cable tray rack, and top frame 11 upper portion sets firmly outwards to extend and press down complex cross arm 13 with the xarm, and cross arm 13 passes through the retaining member and is in the same place with the xarm locking, and the roof-rack splendid attire can be in putting on the shelf hole.
After the top frame is placed on the four corresponding cross arms above the upper frame, the power cable tray frame can be clamped in the top frame hole of the top frame, so that the number of the power cable tray frame storage device for stacking the power cable tray frames up and down is increased, and the effect of saving the storage space is better. Because the top frame of the top frame can be completely placed in the upper frame hole, the size of the top frame hole is inevitably smaller than that of the upper frame hole, and the weight of the power cable tray frame placed in the top frame hole is also inevitably smaller than that of the power cable tray frame placed in the upper frame hole. The total gravity center of the whole power cable tray storage device and the contained power cable tray will rise, but the power cable tray in the top frame hole is lightest, so that the lifting effect of the total gravity center is also minimum, and the stability of the storage of the three power cable trays by the power cable tray storage device cannot be influenced.
The outer end of the hinge shaft 16 is hinged with a side rod 19 through a horizontal hinge shaft 18, the side of the base is hinged with a connecting rod 20 which can swing horizontally outwards, and the tail end of the side rod is connected with the lower end of the connecting rod through a connecting piece 21. After the outer end of the hinge shaft is hinged with the side rod through the horizontal hinge shaft, the side rod can swing around the horizontal hinge shaft. When the side rod is in a disassembly state, the side rod and the two support arms can be folded together, and the storage space is saved. When the side rod is in a use state, the side rod can swing outwards around the horizontal hinge shaft, the effect of an auxiliary supporting tripod can be achieved, and the effect of preventing the whole electric power cable tray rack storage device from inclining in the left and right directions is enhanced. The side of the base is provided with a connecting rod corresponding to the side rod, one end of the connecting rod is hinged with the middle of the side of the base, and the connecting rod can swing in the horizontal plane. Because the length of the side rod is slightly longer than that of the support arm, when the connecting rod swings away from the base and is vertical to the side of the base, the lower end of the side rod just corresponds to the tail end of the connecting rod. A connecting piece is arranged between the tail end of the connecting rod and the lower end of the side rod, and the lower end of the side rod is fixedly connected with the tail end of the connecting rod through the connecting piece. Thus, the side bars, the connecting rods and the tripod constitute a new tripod, which is called a "right-angled tripod" for convenience of description. The connecting rod and the tripod respectively form two right-angle sides of the right-angle tripod, and the side rod forms an inclined side of the right-angle tripod. Likewise, the right-angled tripod is also a triangular structure, and the structural stability of the right-angled tripod is undoubted, so that the right-angled tripod structurally ensures the vertical state of the tripod, and the inclination of the whole power cable tray storage device to the left or the right is fundamentally avoided.
The clamping piece comprises four bottom holes 14 arranged at four corners of the base 1, the lower end of the support arm is fixedly provided with an inserting block 15 which is inserted and matched with the bottom holes 14, and the lower part of the inserting block is in a wedge shape with a narrow lower part and a wide upper part. The bottom hole on the base is matched with the inserting block at the lower end of the supporting arm in an inserting mode, so that the bottom hole and the inserting block have mutual limiting effects in any direction in the horizontal plane, the included angle of the two supporting arms is fixed after the hinge frame is subjected to the gravity of the power cable reel frame, and the structural stability of the tripod is guaranteed. Although the bottom hole and the insertion block have no mutual limiting effect in the vertical direction, after the power cable tray frame is clamped, the weight of the power cable tray frame is enough to enable the insertion block to be firmly inserted into the bottom hole. The lower part of the insert block is set into a wedge shape with a narrow lower end and a wide middle part, so that when the tripod is assembled, people can insert the insert block into the bottom hole quickly, and the assembling time is shortened.
In the power cable tray storage device, the locking member 7 comprises locking holes 22 formed in the cross arm 5 and the upper frame 6, and locking bolts 23 inserted into the locking holes. Adopt locking hole and locking bolt as the retaining member, can insert locking bolt in locking hole between them fast when locking, realize quick locking, help realizing fast assembly.
The upper part of the cross arm 5 is in a wedge shape with a narrower upper end and a wider middle part, the middle part and the lower part of the cross arm are in equal width, four corners of the upper frame 6 are provided with cross rods 24 extending towards the outer cross arm, the cross section of each cross rod 24 is in an n shape with a downward opening part 27, and the opening parts of the cross rods are matched with the cross arm clamping sleeves. The cross rod is designed into the n-shaped structure with the downward opening, so that when the upper frame is placed on the cross rod, the cross rod can be assembled and matched with the cross rod in a buckling mode, and the side wall of the cross rod of the n-shaped structure can play a role in wrapping the cross rod after buckling, so that the two sides of the cross rod can be limited, and the reliability of connection between the cross rod and the cross rod is improved. The upper part of the cross arm is set into a wedge shape with a narrow upper end and a wide lower end, so that the guide effect of the cross rod when the cross arm is buckled on the cross arm can be achieved, the buckling success rate is improved, and the quick assembly is realized.
