In the conventional transmitter, the position and angle of the engine are difficult to adjust due to the overload of the engine, so that the maintenance efficiency of the engine is low, and therefore, a trolley device is required to solve the problem.

Referring to fig. 1, some embodiments of the present application provide a trolley device, which includes a base 3, a fixed platform 2, and a movable platform 1, wherein the fixed platform 2 is fixedly connected with the base 3; the movable platform 1 is slidably connected to the base 3 and is used for being close to or far away from the fixed platform 2 along the first direction a, the movable platform 1 comprises an adjusting component 11 and a supporting table 12 fixedly connected to the adjusting component 11, and the adjusting component 11 is used for adjusting the height of the supporting table 12.

The trolley device is slidably connected to the base 3 by using the movable platform 1, so that the movable platform 1 can slide in the first direction a relative to the fixed platform 2, and the height of the supporting platform 12 is adjusted by the adjusting assembly 11, so that an engine and a gearbox can be stably placed on the trolley device, and the relative positions of the engine and the gearbox can be adjusted by using the movable platform 1 so as to facilitate disassembly and assembly, and the maintenance efficiency of the engine is improved.

It should be noted that, both the fixed platform 2 and the movable platform 1 may be used to carry articles, for example, the fixed platform 2 may be used to carry an engine, the movable platform 1 and the fixed platform 2 cooperate to carry a gearbox on the engine, and the flexibility of the movable platform 1 is utilized to facilitate the disassembly and assembly of the gearbox.

The fixed platform 2 is fixedly connected to the base 3, and the movable platform 1 is slidably connected to the base 3, where the sliding connection manner may be, but is not limited to, a sliding rail, a screw rod, a conveyor belt, etc.

Specifically, the base 3 is placed on the ground, and can connect and carry the fixed platform 2 and the movable platform 1, and the movable platform 1 slides on the base 3 to be close to or far from the fixed platform 2.

The movable platform 1 comprises a supporting table 12 and an adjusting assembly 11, wherein the supporting table 12 is a plane which is arranged on the upper surface of the movable platform 1 and is used for bearing articles, and can move along with the movable platform 1; the adjusting component 11 is arranged below the supporting table 12 and connected with the supporting table 12, and can drive the supporting table 12 to rise or fall so as to adjust the relative height between the supporting table 12 and the upper surface of the fixed platform 2, so as to adapt to the height difference between different loaded articles.

Alternatively, the height of the adjustment assembly 11 may be adjusted in a variety of ways, including but not limited to, cylinders, gears, scissors holders, etc.

That is, when used for carrying articles, the supporting table 12 can translate along with the movable platform 1 to adjust the distance between the movable platform and the fixed platform 2, and can also move in the height direction under the action of the adjusting component 11 to adjust the height difference between the movable platform and the fixed platform 2, so that irregular articles can be carried more conveniently and stably.

It should be noted that, the first direction a is a direction from the movable platform 1 to the fixed platform 2, and the movable platform 1 moves along the first direction a to approach or separate from the fixed platform 2.

In addition, when the trolley device is used for bearing an engine, the base 3 is also provided with a receiving disc which is as large as possible, and the receiving disc is arranged right below the movable platform 1 and the fixed platform 2 and is used for recovering oil in the gearbox, so that the environment is prevented from being influenced.

In one embodiment, referring to fig. 2 and 3, a slide rail 31 is provided on the base 3, and a slider 13 matched with the slide rail 31 is provided on the movable platform 1, where the slider 13 is slidably connected with the slide rail 31. In this way, the sliding block 13 is matched with the sliding rail 31 to ensure the sliding stability of the movable platform 1 and fix the moving track of the movable platform 1.

It should be noted that, the sliding rail 31 on the base 3 extends along the first direction a, and the sliding block 13 is fixedly connected with the movable platform 1 and can be locked on the sliding rail 31 and move relative to the sliding rail 31.

Optionally, the sliding rail 31 may be provided in various ways, such as but not limited to a groove-like structure, a protruding strip-like structure, etc., so that the movable platform 1 can move more smoothly and is not easy to be blocked, and the sliding block 13 should be configured to match with the sliding rail 31, so as to enable the sliding block 13 and the sliding rail 31 to slide with each other and reduce the friction force thereof.

Specifically, as shown in fig. 1 and 2, the sliding rail 31 is disposed at the top of the base 3 and protrudes toward the movable platform 1, so as to facilitate the cooperation of the sliding block 13.

It should be noted that, the movable platform 1 should be further provided with a braking member, which can prevent the movable platform 1 from sliding on the sliding rail 31, so that the movable platform 1 and the fixed platform 2 are relatively fixed.

It is easy to understand that the braking member can be used to fix the movable platform 1 by increasing the friction between the sliding block 13 and the sliding rail 31, and it can have various arrangements, for example, the braking member can be arranged between the sliding block 13 and the sliding rail 31 and can be used to stop the sliding block 13 from moving by abutting against the sliding rail 31, so that the movable platform 1 is fixed; or, the braking members may be disposed at both sides of the sliding block 13 and can press the sliding block 13 to deform the sliding block 13 and press the sliding rail 31 to increase friction force thereof, thereby stopping the mutual movement and fixing the movable platform 1; and the method can be specifically defined according to practical situations.

In one embodiment, referring to fig. 1, the sliding rail 31 is disposed to extend along the first direction a for the movable platform 1 to be away from or close to the fixed platform 2. Thus, the slide rail 31 serves to guide the movement of the movable platform 1 to ensure that the movement track of the movable platform 1 remains fixed.

It should be noted that, the movable platform 1 is slidably disposed on the sliding rail 31, that is, the movement track of the movable platform 1 is fixed, and the movable platform 1 can only move along the sliding rail 31 when moving.

In one embodiment, referring to fig. 2 and 3, the support table 12 is located at the top end of the movable platform 1, and the surface of the support table 12 is kept horizontal, and the adjusting assembly 11 is located below the support table 12 and drives the support table 12 to be raised or lowered by folding. The supporting table 12 is used for carrying articles, and the supporting table 12 is driven to move up and down in a folding mode, so that the upper surface of the supporting table 12 is ensured to be stable and horizontal.

It should be noted that, the supporting table 12 is disposed at the top end of the movable platform 1, that is, the supporting table 12 is a plane on the movable platform surface for placing the articles, and the height of the plane can be adjusted by the adjusting component 11 to adapt to the carried articles.

Wherein the upper surface of the support table 12 should be kept horizontal all the time during the ascent or descent to keep the loaded articles stable.

It should be noted that, the adjusting assembly 11 drives the supporting table 12 to move up and down by folding, and there are various folding manners, such as a scissor rest and similar structures.

When the adjusting assembly 11 is elongated in the height direction, the supporting table 12 can move upwards under the driving of the adjusting assembly 11, and when the adjusting assembly 11 is folded in the height direction, the supporting table 12 moves downwards under the driving of the adjusting assembly 11.

It will be readily appreciated that when the adjustment assembly 11 is folded in the height direction to the lowest height to which the support table 12 moves downwardly, its lowest height should be lower than the height of the upper surface of the fixed platform 2; when the adjusting component 11 extends to the highest position of the supporting table 12 in the height direction, the height of the upper surface of the supporting table 12 should be higher than the height of the upper surface of the fixed platform 2, so that the device has wider application range.

In addition, when the adjusting assembly 11 is extended or contracted in the height direction, a member for fixing the current height should be provided so that the support table 12 can be kept stable in the height direction, and the member may be, but is not limited to, a buckle or the like.

In one embodiment, as shown in fig. 1 and 2, the adjusting assembly 11 includes a fixed frame 111 and a folding frame 112, the fixed frame 111 further includes an upper frame 1111 and a lower frame 1112, the upper frame 1111 is used for carrying the supporting table 12, and the lower frame 1112 is slidably connected with the base 3; the folding frame 112 is disposed between the upper frame 1111 and the lower frame 1112, and includes two connecting rods 1121, where the two connecting rods 1121 are pivoted to each other, and the space between the upper frame 1111 and the lower frame 1112 is enlarged or reduced by folding or unfolding the two connecting rods 1121. Thus, the upper frame 1111 and the lower frame 1112 are respectively disposed at the upper and lower ends of the adjusting unit 11, and the distance between the upper frame 1111 and the lower frame 1112 is changed by the relative movement of the two links 1121 on the folding frame 112, so as to change the height of the support table 12.

It should be noted that, the upper frame 1111 and the lower frame 1112 are respectively located at the upper and lower ends of the adjusting assembly 11 and are disposed opposite to each other, and the adjusting assembly 11 is configured to raise or lower the supporting table 12 by changing the distance between the upper frame 1111 and the lower frame 1112.

It is easy to understand that the upper frame 1111 is fixedly connected to the support table 12, and the lower frame 1112 is connected to the base 3, and the upper frame 1111 is driven to move upward relative to the lower frame 1112 to drive the support table 12 to move upward.

In connection with the above embodiment, the lower frame 1112 is provided with a slider 13 for slidably connecting with the base 3, so that the movable platform 1 can slide along the first direction a.

It should be further noted that the two links 1121 on the folding frame 112 are pivotally connected at the center to form a scissor-like folding frame 112, and the distance between the upper frame 1111 and the lower frame 1112 is changed by the mutual movement between the two links 1121.

Wherein, in the two connecting rods 1121 on the folding frame 112, two ends of each connecting rod 1121 are respectively movably connected to the upper frame 1111 and the lower frame 1112, when the ends of the two connecting rods 1121 connected to the upper frame 1111 are close to each other, the ends of the two connecting rods 1121 connected to the lower frame 1112 are also close to each other simultaneously, at this time, the folding frame 112 is elongated in the height direction, and the supporting table 12 is lifted; when the ends of the two links 1121 connected to the upper frame 1111 are separated from each other, the ends of the two links 1121 connected to the lower frame 1112 are also separated simultaneously, and at this time, the folding frame 112 is contracted in the height direction, and the support table 12 is lowered.

Therefore, the upper frame 1111 or the lower frame 1112 of the folding frame 112 is movably connected, and the upper frame 1111 or the lower frame 1112 should be provided with a region for moving the end of the connecting rod 1121, so that the folding or extending process of the folding frame 112 can be stabilized, and the folding or extending stroke of the folding frame 112 can be controlled by using the region.

In addition, a member for controlling the extension or contraction of the folding frame 112 should be provided on the folding frame 112 so that the folding frame 112 remains fixed after being extended or contracted by a certain stroke.

In one embodiment, as shown in fig. 1 and 2, two ends of the upper frame 1111 and the lower frame 1112 on the same side in the first direction a are respectively provided with a connecting shaft 1113, the connecting shafts 1113 are slidably arranged in the first direction a, one end of one connecting rod 1121 is movably connected with the upper frame 1111, the other end is connected with the connecting shaft 1113 of the lower frame 1112, one end of the other connecting rod 1121 is movably connected with the lower frame 1112, and the other end is connected with the connecting shaft 1113 of the upper frame 1111. Thus, when there are a plurality of folding frames 112, the same connecting shaft 1113 is connected to the same portion of the plurality of folding frames 112, respectively, and the plurality of folding frames 112 can move synchronously through the connecting shaft 1113 by using the plurality of connecting shafts 1113, so as to ensure the stability of the support table 12 in the process of lifting or lowering.

It should be noted that, the upper frame 1111 and the lower frame 1112 are respectively provided with connecting shafts 1113 at two ends in the first direction a, which means that the upper frame 1111 is respectively provided with connecting shafts 1113 at two ends in the first direction a, the lower frame 1112 is respectively provided with connecting shafts 1113 at two ends in the first direction a, that is, the upper frame 1111 and the lower frame 1112 have four connecting shafts 1113 in total, and one folding frame 112 is provided with four ends of four connecting rods 1121, which are respectively connected with the four connecting shafts 1113.

When there are a plurality of folding frames 112, the end portions of the connecting rods 1121 of each folding frame 112 are respectively connected to four connecting shafts 1113, and the synchronous movement of the plurality of folding frames 112 can be controlled by controlling the movement of the connecting shafts 1113.

That is, by controlling the two connection shafts 1113 in the upper frame 1111 to be far from or close to each other, it is possible to control the plurality of folding frames 112 connected to the connection shafts 1113 to be extended or contracted simultaneously, improving the stability of the adjustment assembly 11.

In one embodiment, as shown in fig. 1, 2 and 3, the adjusting assembly 11 further includes an operation portion 113, where the operation portion 113 is at least partially disposed through the upper frame 1111 or the lower frame 1112 and is in driving connection with the corresponding connecting shaft 1113, so as to drive the connecting shaft 1113 to move along the first direction a. Thus, the operation part 113 drives the connecting shaft 1113 to move so as to drive the folding frame 112 to extend or retract, and the height of the support table 12 is controlled.

The operation portion 113 is disposed through the fixed frame 111 and connected to the connection shaft 1113, which means that the operation portion 113 passes through a side surface of the upper frame 1111 or the lower frame 1112 and is in driving connection with the connection shaft 1113 to drive the connection shaft 1113 to move.

The operation part 113 is arranged on the upper frame 1111 or the lower frame 1112 in a penetrating manner along the first direction a, for example, the operation part 113 penetrates through the two connection shafts 1113 along the first direction a, a part of the surface of the operation part 113 penetrating through the first connection shaft 1113 is provided with threads, and a second connection shaft 1113 penetrating through the second connection shaft 1113 is provided with a threaded hole matched with the threaded hole, so that the two connection shafts 1113 are driven to be relatively close to or far from each other through the threads; or a pull rope is arranged between the two connecting shafts 1113, the operating part 113 penetrates through the two sides of the upper frame 1111 or the lower frame 1112 in the first direction A and is connected with the pull rope, and when the operating part 113 is rotated, the pull rope is wound on the operating part 113 to control the distance between the two connecting shafts 1113; the operation portion 113 is not limited to the above-described arrangement, and may be changed according to different arrangements of the folder and the connection shaft 1113.

In one embodiment, as shown in fig. 1 and 4, the adjusting assembly 11 further includes a rotating shaft 114, where the rotating shaft 114 penetrates the supporting table 12, and is used to rotate the supporting table 12 around the rotating shaft 114. Thus, the support table 12 is rotated around the rotation shaft 114, which is beneficial to the omnibearing observation or disassembly of the articles on the movable platform 1.

It should be noted that, the rotating shaft 114 is disposed above the adjusting assembly 11 and can be disposed through the supporting table 12, so as to allow the supporting table 12 to rotate, and the rotating shaft 114 is disposed at one end of the supporting table 12 through which the rotating shaft 114 is disposed, so that the end of the rotating shaft 114 is flush with the upper surface of the supporting table 12, thereby facilitating placement of the articles.

In addition, the rotating shaft 114 should be disposed at the center of the supporting table 12, so that the supporting table 12 is further stably disposed on the adjusting assembly 11 after rotating by a certain angle.

In order to facilitate the fixation of the support table 12 during the rotation of the support table 12 itself, at least two clamping grooves circumferentially distributed around the rotation shaft 114 may be provided in both the support table 12 and the adjustment assembly 11, and corresponding clamping pins may be provided on the other, and the clamping pins may be clamped into the clamping grooves. When the support table 12 rotates around the rotation shaft 114, the bayonet lock can be fixed in the rotation process by rotating from one bayonet lock to the other bayonet lock, and the fixed angle between the two bayonet locks is the rotation angle of the support table 12.

In one embodiment, as shown in fig. 1, 2 and 3, the support table 12 is further provided with a baffle 121, and the baffle 121 is located on a side of the support table 12 away from the fixed platform 2. In this way, the articles on the support table 12 can be further protected by the barrier 121 from tipping or falling off the support table 12 when moving in the first direction a.

It should be noted that the baffle 121 is fixedly connected to the support base 12, and can move or move along with the support base 12, and can also be used as a handle of the support base 12 to facilitate moving or rotating the support base 12.

In one embodiment, as shown in fig. 1, 2 and 4, the movable platform 1 is provided with a locking member 14, the locking member 14 is disposed on one side of the movable platform 1 near the fixed platform 2, the base 3 is provided with a latch 32 matched with the movable platform 1, the latch 32 is disposed on one side of the fixed platform 2 near the movable platform 1, and the locking member 14 can abut against the latch 32 in the first direction a to fix the movable platform 1 and the fixed platform 2 relatively. Thus, the movable platform 1 is locked with the fixed platform 2 in the first direction A, so that the movable platform and the fixed platform are relatively fixed in the first direction A, and the stability of the trolley device is improved.

It should be noted that, the fact that the locking member 14 abuts against the lock catch 32 in the first direction a means that the force of the locking member 14 abutting against the lock catch 32 is along the first direction a, so that the abutting surface of the locking member 14 and the lock catch 32 is located at one side of the locking member 14 opposite to the fixed platform 2, and the locking member 14 cannot move in a direction away from the fixed platform 2 through abutting, so as to achieve the effect of locking the movable platform 1.

In order to further improve the convenience of mutual locking between the movable platform 1 and the fixed platform 2, a self-locking structure may be provided between the locking member 14 and the lock catch 32, that is, when the movable platform 1 moves along the first direction a to approach the fixed platform 2, the locking member 14 can move to automatically abut against the lock catch so as to limit the movable platform 1; when the restriction of the movable platform 1 needs to be released, the movable platform 1 can be unlocked by manually staggering the locking piece 14 and the buckle.

Alternatively, the locking member 14 and the lock catch 32 may be provided in any manner as long as the movable platform 1 is limited to move in a direction away from the fixed platform 2, which may be, but not limited to, various self-locking mechanisms or quick-release mechanisms commonly used in the market.

In one embodiment, as shown in fig. 1, 2 and 5, the fixed platform 2 includes a fixed frame 21 and a mounting member 22, one end of the fixed frame 21 is connected to a side of the fixed platform 2 away from the movable platform 1, the other end is rotatably connected to the mounting member 22 through an axis extending along the first direction a, and a mounting hole 221 is formed in the mounting member 22. Thus, the mounting holes 221 can be used for fixing the engine to avoid rollover of the engine, and the mounting holes 221 on the mounting piece 22 can rotate relative to the fixing platform 2, so that the engine fixing device is suitable for fixing more kinds of engines.

It should be noted that, the fixing frame 21 and the mounting member 22 are used for fixing the engine when the engine is disassembled, because the engine can cause the instantaneous change of the center of gravity position of the engine due to the instantaneous disassembly of the gearbox, the occurrence of rollover can be avoided by fixing the mounting hole 221, and the stability of the trolley device is ensured.

Also, the mounting member 22 is provided to be rotatable to enable movement of the mounting hole 221 for adapting to most different models of engines.
