Description

Quick combination climbing tool for power system

technical field

The utility model relates to a fast combined climbing tool for an electric power system.

Background technique

At present, when maintaining the power system in the field, generally only ladders can be carried for climbing. Therefore, ladders have become a necessary configuration for electric maintenance vehicles or electric emergency repair vehicles. The ladders currently used on electric maintenance vehicles are generally of a folding structure or a carriage structure, wherein the folding structure is generally a structure in which two ladder sections are hinged together through hinges. When this kind of folding ladder is in use, just unfold the two ladder sections and lock them with locking parts, and the operation is relatively simple. The carriage structure is generally also composed of two ladder sections, but the two are not in a folding or hinged relationship, but a sliding fit relationship that can slide in the direction of extension. When this kind of ladder is in use, it is also necessary to slide and unfold the two sections of the ladder, and then lock it with a locking piece to use it, and the operation is relatively simple. Currently, ladders with this carriage structure are used the most. Regardless of the ladder of any structure, although it is easy to operate in use, it has the following shortcomings: 1. Because the ladder sections are all ready-made ladder structures, they have fixed dimensions, especially wide width, whether they are stored or It needs to occupy a large space when carrying it, which is very inconvenient; 2. It has an integral structure and cannot be disassembled, so it is heavy and requires two people to operate it when moving; 3. It has a single function, except for electric climbing, there is no other The purpose is a single-purpose tool, and such a tool will inevitably reduce the payload of the electric maintenance vehicle; 4. The length is fixed, and the length of the ladder cannot be adjusted freely according to the needs of the site, especially to extend the length of the ladder, and because the carriage structure has overlapping parts, Therefore can not make full use of the total length of two section ladder sections.

In addition, in the daily work of the power system, it is often necessary to conduct electrification experiments on various power equipment and tools, or to use power tools for maintenance, and AC power is required at this time. There are two main ways to obtain AC power, one is the power supply on the on-site power supply equipment, and the other is the generator set. Since the maintenance work in the field is usually done with power cut off, very long cables need to be laid, which is neither convenient nor safe. Even if there is occasional live work on site, not only climbing tools, such as ladders, etc. are needed to obtain electricity on site, but it will also have an adverse effect on electricity metering and electricity safety. Therefore, when using an AC power source for operations in the field, it is generally necessary to carry small and medium-sized equipment such as generator sets.

Due to the heavy weight of small and medium-sized equipment such as generator sets, a three-phase diesel generator weighs about one ton, and generally requires 5 or 6 people to lift it up. Therefore, it should be stored outdoors or in a warehouse, moved, and unloaded, transported, and loaded in the field. All very inconvenient. The cost of buying a forklift is too high (about 100,000 yuan per set), and the cost of renting a crane is too high. It is impossible to lift it manually, and there are great risk factors, which may easily cause crushing, crushing and smashing injuries to the staff. . When moving small and medium-sized equipment such as generator sets, there are three operation methods: 1. Rent a crane for loading, and then use the crane to unload the truck when it is used up. The crane hoisting takes about 40 minutes to an hour (including dispatching vehicles and arrival time), It is a waste of time and cost, and it is necessary to reserve a crane in advance, which seriously affects the work progress. 2. To buy a forklift, a forklift is about 100,000 yuan, which is relatively expensive, and the forklift cannot be dragged to the field operation site by a maintenance vehicle, so a driver can only be arranged to drive the forklift, which is very uneconomical. 3. Use a manual trailer for transfer. First, transport the generator to the maintenance workshop with a manual trailer (storage of such equipment is not allowed due to other plans in the maintenance workshop), and then use the lifting truck in the maintenance workshop to perform hoisting The car takes about 20 minutes. Because the storage place of the generator is still some distance away from the maintenance workshop, it is very cumbersome and troublesome to unload the generator in the same way after use. This method is only suitable for transfer within the company, not for field work.

Contents of the invention

The technical problem to be solved by the utility model is to provide a quick combined power system climbing tool with reasonable structure, small space occupation, easy to carry, adjustable length, can assist lifting heavy objects, and simple operation for the above defects.

In order to solve the above-mentioned technical problems, the structural characteristics of the rapid combined climbing tool for the electric power system are as follows: it includes four or more even-numbered pillars, an upper arm is respectively hinged on the left and right sides of the upper end of the pillar, and an upper arm is respectively hinged on the front and rear sides of the middle and upper part of the pillar. The lower arm also includes several cross-arms, the pillars, the upper arm, the lower arm and the cross-arms are evenly distributed with fixing holes, and also includes fixing parts matched with the fixing holes, the two lower arms of each pillar can extend upward along the pillar and The upper part of the pillar is fixed together with the fixing piece, and the two pillars form a group, and the two corresponding upper arms of the two pillars in each group can cross upward to form an X frame and be fixed together by the fixing piece, and the remaining two upper arms can cross downward It is X-shaped and fixed together with the corresponding pillars through the fixing parts. Each group is arranged up and down in sequence. The lower parts of the two pillars of the upper group can be inserted between the lower arms of the lower group and fixed together through the fixing parts.

The power system fast combination climbing tool realizes small space occupation, convenient carrying, adjustable length, can assist in lifting heavy objects, and is easy to operate through the combined structure of deformable hinged units.

The combined structure of the deformable hinged unit means that the quick combined climbing tool for the electric power system contains a plurality of hinged units, usually four, or an even number of more than four. In the following, four hinged units are taken as an example for illustration, and the power system rapid combination climbing tool with more than four even-numbered hinged units is similar to this, and will not be described in detail. The hinge unit includes a vertically arranged pillar, and two upper arms are hinged on the upper end of the pillar. For convenience of description, the hinge axis between the upper arm and the pillar is called the upper hinge axis. The two upper arms are respectively located on the left and right sides of the pillar, and both can swing up and down around the upper hinge shaft. The upper middle part of the pillar, that is, the pillar part near the upper hinge axis, is hinged with two lower arms. For convenience of description, the hinge axis between the lower arm and the pillar is called the lower hinge axis. The two lower arms are respectively located on the front and rear sides of the pillar, and can swing up and down around the lower hinge shaft. Fixing holes are evenly distributed on the pillar, the upper arm and the lower arm, and fixing pieces interspersed with the fixing holes are also included to facilitate positioning and fixed connection through the fixing pieces and the fixing holes. In this way, the pillar, its upper hinged upper arm and lower arm, as well as the fixed part cooperating with it, constitute a hinged unit.

The rapid combination climbing tool for the electric power system includes four hinged units, and the four hinged units are divided into two groups in pairs. Thus, each set consists of two struts, four upper arms and four lower arms. For convenience of description, the two pillars of the same group are called the first pillar and the second pillar, and the upper arm and the lower arm on it are respectively called the first upper arm, the first lower arm, the second upper arm, and the second lower arm.

The two lower arms of each pillar in each group extend upwards, and the extension direction of the lower arm is consistent with the extension direction of the pillar. In each hinge unit, the two lower arms and the part of the pillar located between the upper hinge shaft and the lower hinge shaft are fixedly connected together by a fixing piece, so that the hinge unit forms a straight bar structure with a longer length. For the convenience of description, the straight rod structure, that is, the structure in which the pillar and the two lower arms are fixed in the same direction, is called a ladder rod. The ladder rods are much longer than the pillars and are nearly twice as long as the pillars. Because the interval between the two lower arms is by the pillars, a strip-shaped gap is formed above the pillars and between the two lower arms.

An upper arm of each set of first pillars extends obliquely downward to the same side of the second pillars, and is fixed together with fixing pieces through the corresponding fixing holes of the two. Similarly, the second upper arm on the other side of the second pillar extends obliquely downward to the corresponding side of the first pillar, and is fixed together with a fixing member through the corresponding fixing holes of the two pillars. That is to say, the two pillars of the same group are connected obliquely to each other through their respective upper arms. In this way, the two upper arms cross to form an X-shaped structure, which is called an X-frame for convenience of description. Under the support of the X frame, two pillars and two upper arms form two triangular structures. According to the triangular stability principle, this structure is the most stable. Therefore, the two pillars and the two upper arms of the same group constitute a stable flat support or plank support, which effectively ensures the structural stability of the rapid combination climbing tool of the power system.

The remaining two upper arms of the same group extend obliquely upward towards each other and cross in an X shape, also forming an X frame. The intersections of the two upper arms are correspondingly fixed together through the fixing parts, so that the X-frame becomes a fixed structure. Because the two pillars in the same group are a fixed integral structure, the X frame extending above it must also be a fixed integral structure under the support of the pillars or plate-shaped supports. In this way, in each group, a trapezoidal structure with two ladder bars as vertical supports and two X frames as lateral supports is formed. For the convenience of description, the fixed combination of the X frame and the ladder bar is called a ladder section, that is to say, each group constitutes a ladder section. Like this, in this power system quick combination climbing tool, just combined into two stair sections.

These two groups or two stair sections are set up and down in the same direction in terms of positional relationship. For the convenience of description, the group or stair section at the top is called the upper group or stair section, and the group or stair section at the bottom is called the upper group or stair section. It is the next group or the next ladder section. The lower parts of the two pillars of the upper stair section are inserted between the two lower arms of the lower stair section, that is, in the above-mentioned gap, and the overlapping parts of the upper stair pillars and the lower arms of the lower stair section are locked together by the fixing piece . In this way, the two ladder rods are fixedly connected to form a longer straight rod structure. For the convenience of description, this straight rod structure is called a ladder column. Because the above-mentioned gaps are strip-shaped, the overlapping and matching range of the pillars of the upper stair section and the lower arm of the lower stair section is very large, and it can be freely adjusted according to specific climbing requirements during use. The adjustment range of the length of the ladder column is roughly between three times the length of the column and four times the length of the column. If the length of the pillar is set to 1 meter, the length of the ladder column is in the range of 3-4 meters. And if the folding structure ladder that uses at present will meet the requirement of climbing a height of 4 meters, the length after its folding also will be 2 meters at least. And the ladder of slide frame structure has overlapping parts, so if want to meet the climbing requirement of 4 meters, its slide frame length must be greater than 2 meters. The 2-meter slide or ladder section cannot fit inside the vehicle body of the electric maintenance vehicle, and can only be tied to the side or top of the vehicle. Not only is it inconvenient to tie, it takes up a lot of space, it is not beautiful, and there is a risk of traffic violations. The power system quick combination climbing tool only needs four 1-meter-long hinged units, not only the length is completely within the storage range of the vehicle body, but also small in size, which is very convenient for storage, carrying or picking and placing.

After the ladder rods are fixed into ladder columns, there are four X-frames erected between the two ladder columns, and each X-frame contains two crossed upper arms, so a total of eight horizontal supports are formed between the two ladder columns, completely It can be used for stepping on when climbing, so that it can be assembled into a "ladder" for climbing.

When it needs to be disassembled after climbing, you only need to disassemble the fixing parts installed on the upper arm and the lower arm, and the power system quick combination climbing tool can be quickly restored to four hinged units, and the operation is very simple. When assembly is required, the above-mentioned operation process is to assemble the hinged units in pairs to form stair sections, and then plug the two stair sections up and down. The operation is also very simple and fast, which greatly improves the work efficiency, especially on site. work efficiency.

When working on the power system site, it is often necessary to use heavy equipment such as generators. This kind of equipment is usually transported to the site by electric maintenance vehicles and carried up and down the stage by multiple workers, which is extremely dangerous. You can also hire a crane to unload and load the vehicle. Either way, it is time-consuming and laborious. Because the power system quick combination climbing tool is composed of multiple hinge units, it has a certain hinge deformation function. The specific deformation process is to first disassemble the "ladder" and divide it into two groups of four hinged units, and the four hinged units are erected on the four corners of the square; Fix and cross diagonally downward to form an X frame, and the lower end of the X frame is fixedly connected with the two pillars through the fixing piece, so that the X frame and the two pillars form a triangular fixed support structure; in this process, the two pillars of each pillar The lower arm extends obliquely to the upper and lower parts of another group of adjacent pillars and is fixed with a fixing piece. In this way, two X frames are formed between the adjacent pillars in the two groups, and the X frames are connected with the connected pillars. The two pillars also form a triangular fixed support structure. Therefore, the four pillars are connected to form a fixed cube bracket; the two remaining upper arms in the same group are fixed and connected obliquely through the fixing parts to form an X frame. For the convenience of description, the X The frame is called the upper X frame, and the cross arm is arranged between the upper X frames of the two groups. For convenience of description, the cross arm is called the support cross arm, and the remaining cross arm is called the lever cross arm. In this way, a simple lifting or hoisting device is formed. When in use, the support cross arm erected on the cube support can be used as a fulcrum to pry or lift heavy objects through the lever cross arm, which meets the requirements of lifting heavy objects on the job site. need. After use, the hoisting or hoisting device can be quickly restored to four articulated units and a plurality of cross-arms by removing the subsequently added fixing parts, and the operation is very simple.

The above-mentioned deformed structure is directly assembled by hinge units. In actual use, the "ladder" can also be restored into two ladder sections by disassembling the fixing parts, and then the ladder sections can be restored into the support fixedly connected by the X frame and the pillars. Finally, the two supporting structures are fixed and combined into a cube bracket through the lower arm and the fixing piece, and then the upper X frame and the supporting cross arm are set up to lift the heavy object. The deformation process is similar and will not be described in detail here.

The power system rapid combination climbing tool uses the hinged unit as the combination unit. It is small in size, not only convenient to carry, transport, and store, but also can quickly assemble or build the climbing device and its devices on the job site. This requirement greatly simplifies the tool carrying capacity of the electric maintenance vehicle.

As an improvement, the lower parts of each set of two pillars are correspondingly fixedly connected with a cross arm.

Because the X frame between the pillars is arranged on the upper part of the pillar, it is suspended between the lower parts of the two pillars, which is very inconvenient when climbing from the ground. After setting the cross arm at the lower part of the pillar, it can provide support for climbing the "ladder", which is more humane.

As an improvement, the lower ends of the lower two pillars are correspondingly fixed with cross arms.

The lower two pillars are the two pillars at the bottom of the ladder pillars. After the lower ends of the two pillars are connected to the cross arm, the contact area between the lower end of the "ladder" and the ground can be increased, which increases the supporting area and supporting force, and effectively prevents the sinking of the "ladder" during climbing. Suitable for field work.

To sum up, the power system rapid combination climbing tool with the above structure has a reasonable structure, takes up little space, is easy to carry, has adjustable length, can assist in lifting heavy objects, and is easy to operate, especially suitable for power maintenance.

Detailed ways

As shown in the figure, the rapid combined climbing tool for electric power system includes four or more even-numbered pillars 1 , and in this embodiment, four pillars are taken as an example for illustration. The pillar 1 is a square tube made of aluminum alloy profile, which can not only ensure the support strength, but also effectively reduce the weight. The upper end of the pillar 1 is hinged with two upper arms 2 . For convenience of description, the hinge axis between the upper arm 2 and the pillar 1 is called the upper hinge axis. The two upper arms are respectively located on the left and right sides of the pillar, and both can swing up and down around the upper hinge shaft. Two lower arms 3 are hinged on the upper part of the pillar 1, that is, the pillar part close to the upper hinge axis. For convenience of description, the hinge axis between the lower arm and the pillar is called the lower hinge axis. The two lower arms 3 are respectively located on the front and rear sides of the pillar, and can swing up and down around the lower hinge shaft. The pillar 3, the upper arm 2, and the lower arm 3 are evenly distributed with fixing holes 5, and also include a fixing piece 6 interspersed with the fixing hole 5, so as to facilitate positioning and fixed connection through the fixing piece 6 and the fixing hole 5. In this way, the pillar, the upper arm 2 and the lower arm 3 hinged on its upper part, and the fixing piece 7 matched therewith constitute a hinge unit, as shown in Fig. 2 and Fig. 3 .

In the quick combination climbing tool of the power system, four pillars 1 are included, that is, four hinge units are included. The four hinged units are divided into two groups in pairs. In this way, each group includes two pillars 1 , four upper arms 2 and four lower arms 3 . For convenience of description, the two pillars of the same group are called the first pillar and the second pillar, and the upper arm and the lower arm on it are respectively called the first upper arm, the first lower arm, the second upper arm, and the second lower arm.

The two lower arms 3 of each pillar 1 in each group extend upwards, and the extension direction of the lower arms 3 is consistent with the extension direction of the pillar. In each hinge unit, the two lower arms 3 and the part of the pillar 1 between the upper hinge shaft and the lower hinge shaft are fixedly connected together by a fixing member, so that the hinge unit forms a longer straight rod structure. For the convenience of description, the straight rod structure, that is, the structure in which the pillar 1 and the two lower arms 3 are fixed in the same direction is called a ladder rod. The ladder rods are much longer than the pillars and are nearly twice as long as the pillars. Because the interval between the two lower arms 3 is by the pillars, a strip-shaped gap is formed above the pillars and between the two lower arms.

An upper arm of each set of first pillars extends obliquely downward to the same side of the second pillars, and is fixed together with fixing pieces through the corresponding fixing holes of the two. Similarly, the second upper arm on the other side of the second pillar extends obliquely downward to the corresponding side of the first pillar, and is fixed together with a fixing member through the corresponding fixing holes of the two pillars. That is to say, the two pillars 1 of the same group are connected obliquely to each other through their respective upper arms 2, so that the two upper arms 2 intersect to form an X-shaped structure, which is called an X-frame for convenience of description. Under the support of the X frame, the two pillars 1 and the two upper arms 2 constitute two triangular structures. According to the triangular stability principle, this structure is the most stable. Therefore, the two pillars 1 and the two upper arms 2 of the same group constitute a stable flat support or plank support, which effectively ensures the structural stability of the rapid combination climbing tool of the power system.

The remaining two upper arms of the same group extend obliquely upward towards each other and cross in an X shape, also forming an X frame. The intersections of the two upper arms are correspondingly fixed together through the fixing parts, so that the X-frame becomes a fixed structure. Because the two pillars in the same group are a fixed integral structure, the X frame extending above it must also be a fixed integral structure under the support of the pillars or plate-shaped supports. In this way, in each group, a trapezoidal structure with two ladder bars as vertical supports and two X frames as lateral supports is formed. For the convenience of description, the fixed combination of the X frame and the ladder bar is called a ladder section, that is to say, each group constitutes a ladder section. Like this, in this power system quick combination climbing tool, just combined into two stair sections.

These two groups or two stair sections are set up and down in the same direction in terms of positional relationship. For the convenience of description, the group or stair section at the top is called the upper group or stair section, and the group or stair section at the bottom is called the upper group or stair section. It is the next group or the next ladder section. The lower parts of the two pillars of the upper stair section are inserted between the two lower arms of the lower stair section, that is, in the above-mentioned gap, and the overlapping parts of the upper stair pillars and the lower arms of the lower stair section are locked together by the fixing piece . In this way, the two ladder rods are fixedly connected to form a longer straight rod structure. For the convenience of description, this straight rod structure is called a ladder column. Because the above-mentioned gaps are strip-shaped, the overlapping and matching range of the pillars of the upper stair section and the lower arm of the lower stair section is very large, and it can be freely adjusted according to specific climbing requirements during use. The adjustment range of the length of the ladder column is roughly between three times the length of the column and four times the length of the column. If the length of the pillar is set to 1 meter, the length of the ladder column is in the range of 3-4 meters. And if the folding structure ladder that uses at present will meet the requirement of climbing a height of 4 meters, the length after its folding also will be 2 meters at least. And the ladder of slide frame structure has overlapping parts, so if want to meet the climbing requirement of 4 meters, its slide frame length must be greater than 2 meters. The 2-meter slide or ladder section cannot fit inside the vehicle body of the electric maintenance vehicle, and can only be tied to the side or top of the vehicle. Not only is it inconvenient to tie, it takes up a lot of space, it is not beautiful, and there is a risk of traffic violations. The power system quick combination climbing tool only needs four 1-meter-long hinged units, not only the length is completely within the storage range of the vehicle body, but also small in size, which is very convenient for storage, carrying or picking and placing.

After the ladder rods are fixed into ladder columns, there are four X-frames erected between the two ladder columns, and each X-frame contains two crossed upper arms, so a total of eight horizontal supports are formed between the two ladder columns, completely It can be used for stepping on when climbing, so that it can be assembled into a "ladder" for climbing.

When it needs to be disassembled after climbing, you only need to disassemble the fixing part 6 installed on the upper arm 2 and the lower arm 3, and the power system quick combination climbing tool can be quickly restored to four articulated units, and the operation is very simple. When assembly is required, the above-mentioned operation process is to assemble the hinged units in pairs to form stair sections, and then plug the two stair sections up and down. The operation is also very simple and fast, which greatly improves the work efficiency, especially on site. work efficiency.
