Description

Technical Field

[0001] The utility model relates to the technical field of transmission handling tools, in particular to a transportation tool for detecting an electric mining truck transmission. Background Technique

[0002] A transmission, also known as a gearbox, is a mechanism used to change the speed and torque from the engine. It can fix or shift gears to change the transmission ratio between the output shaft and the input shaft. The transmission on an electric mining truck cooperates with the automatic speed regulation of the motor to improve the torque change range of the mining truck motor and enhance the load capacity and climbing ability of the mining truck. It is an important power component.

[0003] When the gearbox is disassembled and transported, tools are needed. Because the truck gearbox is heavy and relatively large in volume, it is difficult for manual handling. Moreover, during the gearbox test, various tests need to be carried out on the transmission, which requires the transmission to be repeatedly disassembled, assembled and moved. This process inevitably involves the use of handling tools. Manual handling is difficult and prone to danger.

[0004] For example, a transportation tool for detecting an electric mining truck transmission proposed in the literature number "CN112607665A" includes a frame, and the four corners of the bottom of the frame are supported by telescopic feet. It is recorded in paragraph

[0055] of the specification that the telescopic feet are fixedly connected to the periphery of the frame, and universal wheels are provided at the bottom ends of the telescopic feet. The telescopic feet include hydraulic telescopic rods, upper support rods and lower support rods. Therefore, this solution controls the lifting through four hydraulic telescopic rods, and the four hydraulic telescopic rods need to be lifted and lowered simultaneously. There is no device and method for controlling the simultaneous lifting and lowering of the four hydraulic telescopic rods in the literature, resulting in time-consuming and laborious operation when operating the four hydraulic telescopic rods separately, and the transportation process is time-consuming.

[0021] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0022] Please refer to Figures 1 to 4 , the present invention provides a technical solution: a transportation tool for detecting an electric mining truck transmission, including a first U-shaped frame 1 and a second U-shaped frame 7 parallel to and above the first U-shaped frame 1. Both sides of the first U-shaped frame 1 and the second U-shaped frame 7 are connected by lifting frames. As Figure 1 and Figure 2 shown, the lifting frames on both sides respectively include a first support arm 5 and a second support arm 6. The middle parts of the first support arm 5 and the second support arm 6 are crossed and rotatably connected, that is, the first support arm 5 and the second support arm 6 form an "X"-shaped frame body, and the first support arm 5 and the second support arm 6 can realize height changes when opening and closing;

[0023] The top of the first support arm 5 and the bottom of the second support arm 6 are both rotatably installed on the slide block 2. The bottom of the second U-shaped frame 7 and the top of the first U-shaped frame 1 are respectively provided with guide rails 3 corresponding to the slide block 2, and the slide block 2 is respectively slidably arranged on the guide rails 3; and the top of the second support arm 6 is rotatably connected to the second U-shaped frame 7, and the bottom of the first support arm 5 is rotatably connected to the first U-shaped frame 1. Therefore, when the first support arm 5 and the second support arm 6 open and close, one ends of the first support arm 5 and the second support arm 6 respectively slide along the guide rail 3. When the angle between the first support arm 5 and the second support arm 6 becomes smaller, the overall height of the lifting frame increases, and when the angle between the first support arm 5 and the second support arm 6 becomes larger, the height of the lifting frame decreases.

[0024] As Figure 1As shown in the figure, in the middle of one end of the first U-shaped frame 1 away from its opening, there is a strip-shaped support 21 extending outward. Below the end of the strip-shaped support 21, there is a steering wheel. At both ends of the first U-shaped frame 1 close to its opening, support wheels 4 are respectively installed. Inside one end of the strip-shaped support 21 away from the first U-shaped frame 1, a vertically downward rotating seat 19 is rotatably installed. Below the end of the rotating seat 19, there is a steering wheel. At the top of the rotating seat 19, a rotating shaft 18 is coaxially connected. The top of the rotating shaft 18 is perpendicularly connected to the middle of the handle 16;

[0025] There are two types of steering wheels in this application;

[0026] The first type is, as Figure 1 shown in the figure, the steering wheel includes two traveling wheels 23. The two traveling wheels 23 are respectively rotatably installed at both ends of the wheel shaft 20. The middle of the wheel shaft 20 is rotatably installed in the U-shaped seat 22. The U-shaped seat 22 has an opening facing downward, and its top is connected to the lower end of the rotating seat 19. When the operator holds the handle 16, the operator can manually rotate the rotating shaft 18 to drive the steering wheel to rotate. The two traveling wheels have a large span and good support, so that the two traveling wheels 23 can support on the ground more stably at the same time. Moreover, when the road surface is uneven, the two traveling wheels can also rotate around the U-shaped seat 22 to adjust their own positions, so that the two traveling wheels can always contact the ground.

[0027] The second type is, as Figure 4 shown in the figure, the steering wheel is a universal wheel arranged at the bottom of the rotating seat 19. The universal wheel is simpler and can be directly pushed to move forward.

[0028] Furthermore, at the top of the strip-shaped support 21 close to one end of the first U-shaped frame 1, a vertical support 14 is perpendicularly installed. On the side of the vertical support 14, there is a lead screw lifting mechanism connected to the end of the second U-shaped frame 7. The specific structure of the lead screw lifting mechanism includes a transmission lead screw 27 arranged on the side of the vertical support 14 close to the second U-shaped frame 7. A connecting frame 29 is threadedly connected to the transmission lead screw 27. The other end of the connecting frame 29 is connected to the end of the second U-shaped frame 7;

[0029] Both ends of the transmission lead screw 27 are rotatably installed in the bearing block 26, and the bearing block 26 is installed on the vertical bracket 14; the top of the transmission lead screw 27 is connected to the output end of the gearbox 11, the input end of the gearbox 11 is connected to the drive motor 13, and both the drive motor 13 and the gearbox 11 are arranged on the vertical bracket 14. In order to increase the output torque of the drive motor 13, a planetary speed reducer 12 can be installed on the output shaft of the drive motor 13, and the output shaft of the planetary speed reducer 12 is connected to the gearbox 11. Therefore, the drive motor can drive the transmission lead screw 27 to rotate after two-stage speed reduction through the planetary speed reducer 12 and the gearbox 11, so that the second U-shaped frame 7 is lifted and lowered under the drive of the lead screw lifting mechanism. When the second U-shaped frame 7 is lifted and lowered, it can drive the first support arm 5 and the second support arm 6 located on both sides of it to perform an opening and closing movement, so that the lifting of the second U-shaped frame 7 is kept stable.

[0030] Further, as Figure 1 and Figure 2 shown, at least two support rods 9 are further provided on the top of the second U-shaped frame 7. The support rods 9 are perpendicular to the vertical bracket 14. A number of spaced limit grooves 25 are provided at the edges of the second U-shaped frame 7 at both ends of the support rods 9. Both ends of the support rods 9 are respectively placed in the limit grooves 25. During use, the position of the support rods 9 is placed corresponding to the connection point of the gearbox. Due to the different sizes of the gearboxes, the positions of the support rods 9 may be different. Therefore, by placing both ends of the support rods 9 in the limit grooves 25, the position of the support rods 9 can be changed to better correspond to the gearbox. During use, the gearbox is bound by a pull rope, and the free end of the pull rope is fixed on the support rod 9; and strip-shaped seats 8 are further provided under the support rods 9, and a plurality of hanging holes 10 are opened on the strip-shaped seats 8;

[0031] Specifically, when this application is in use, the first U-shaped frame 1 is pushed to the position of the gearbox, and the gearbox is placed in the first U-shaped frame 1. Of course, at the initial stage, the second U-shaped frame 7 should be lowered to the lowest position, and the support rods 9 should be located above the gearbox. Then, both ends or other positions of the gearbox are bound by a pull rope (as shown by the arrow A in Figure 1 and Figure 2 ), and then the two ends of the pull rope are hooked into the hanging holes 10 through hooks. Then, the drive motor 13 is controlled to drive the transmission lead screw 27 to rotate, so that the transmission lead screw 27 drives the second U-shaped frame 7 to lift upward, so that the second U-shaped frame 7 lifts the gearbox.

[0032] Furthermore, because the mass of the gearbox is relatively large, it is relatively laborious to transport the gearbox after it is lifted. Therefore, the support wheel 4 of this application is an electric drive wheel. The support wheel 4 includes a hub motor and a tire located on the hub motor, and the gearbox can be transported through the driving force of the electric hub. As Figure 2As shown, the specific installation method of the in-wheel motor is to install it on the support shaft 30, and the support shaft 30 is arranged on the first U-shaped frame 1 through the mounting seat 28. During installation, the electric drive wheel needs to be fixed so that the rotor of the in-wheel motor can rotate when powered on;

[0033] Both the drive motor 13 and the in-wheel motor need electricity during operation. Therefore, battery boxes 24 are symmetrically arranged on both sides of the first U-shaped frame 1 away from the open end, and rechargeable battery packs are provided in the battery boxes 24; the rechargeable battery packs are connected to a controller through wires. The symmetrically arranged rechargeable battery packs can balance the first U-shaped frame 1. The controller is respectively connected to the drive motor 13 and the support wheel 4 (in-wheel motor) through wires, and the charging ports of the rechargeable battery packs are arranged on the battery boxes 24, and the charging ports are connected to the controller through wires for convenient charging. As Figure 1 shown, a throttle switch 15 connected to the controller through a wire is provided at one end of the grip 16, and a switch for controlling the forward and reverse rotation of the drive motor 13 is also provided on the grip 16, and the switch is connected to the controller through a wire. Therefore, when the operator holds the grip 16, the drive motor 13 and the support wheel 4 can be respectively controlled through the switch and the throttle switch 15;

[0034] It should be noted that when the support wheel 4 travels with power on, the movement speed is slow. The traveling speed of the support wheel 4 should preferably not exceed the walking speed to avoid excessive speed causing the gearbox to shake.

[0035] Based on the above embodiments, it can be further optimized that the controller is arranged in the control box 17, and the control box 17 is installed on the vertical bracket 14.

[0036] Based on the above embodiments, it can be further optimized that a guide rail is arranged on the surface of the vertical bracket 14, and the guide rail is connected to the connecting frame 29 through a slider to make the up and down movement of the connecting frame 29 more stable.
