Description

Technical Field

[0001] The utility model belongs to the technical field of cargo transportation, and more specifically, relates to a multifunctional material pushing vehicle and a material transporting device. Background Art

[0002] Rail transit has become the most convenient means of transportation, and the construction of rail transit is a very complicated procedure. During track laying, workers will combine rails and sleepers on the ground in advance, adjust the distance between rails and sleepers, and fasten them together with fasteners to form rails, which will then be transferred to the construction area by a large gantry crane on the ground, and then moved to the pre-laid steel bars by a small gantry crane.

[0003] During track laying, materials such as electromechanical installation are generally transported by human-powered flatbed transporters. Ordinary flatbed transporters are assembled by welding steel frames and casters. The front and rear wheels of existing transporters are mostly located on the same plane, which is convenient for transportation on a flat road. However, when driving on a sloped road, the vehicle body will tilt, which not only increases the labor of pushing the transporter, but also the tilted vehicle body easily causes the materials on the transporter to fall off. Even during transportation, the vehicle body is unstable due to the tilt of the vehicle, and it is easy to lose control of the flatbed vehicle due to landslides, resulting in rollover.

[0041] Please also read Figure 1 to Figure 2 The multifunctional material pusher and material transport device provided by the utility model are now described. The multifunctional material pusher comprises a vehicle body 1 and a climbing assembly 2. The vehicle body 1 has a plurality of groups of running wheels 101 arranged in sequence along the front-rear direction. The climbing assembly 2 comprises a mounting frame and a climbing wheel 203 rotatably connected to the mounting frame. The mounting frame is detachably connected to the vehicle body 1. After the mounting frame is connected to the vehicle body 1, the climbing wheel 203 forms a height difference with the running wheel 101 in the up-down direction.

[0042] Compared with the prior art, the multifunctional material pusher provided by the utility model does not need to install the climbing component 2 when driving on the horizontal ground, and the vehicle body 1 is moved by the rotation of the driving wheel 101. When driving to the slope section, the mounting frame is connected to the vehicle body 1, and the climbing wheel 203 forms a height difference with the driving wheel 101, and when the storage surface of the vehicle body 1 is kept horizontal, the climbing wheel 203 is located below the driving wheel 101. When the vehicle body 1 drives to the slope section, the driving wheel 101 is located at a higher position of the slope section, and the climbing wheel 203 is located at a lower position of the slope section. Since the height difference between the climbing wheel 203 and the driving wheel 101 levels the height difference formed by the slope, the storage surface of the vehicle body 1 continues to remain horizontal. The scheme in the utility model can determine whether to use the climbing component 2 according to the actual road conditions of the construction site, and the storage surface of the vehicle body 1 can be kept horizontal even on the slope section, avoiding the problem of material falling or the tilt of the vehicle body 1 causing the vehicle to overturn.

[0043] Optionally, the mounting member 3021 is connected to the front side and / or the rear side of the vehicle body 1 .

In this embodiment, the mounting frame can be interference fit with the fixing tube 102, or can be screwed or clamped with the fixing tube 102. For example, the mounting frame and the fixing tube 102 are respectively provided with corresponding threaded holes, and bolts are inserted into the threaded holes to achieve a fixed connection between the mounting frame and the fixing tube 102.

[0047] In some embodiments, see Figure 1 The multifunctional material pushing vehicle also includes a steering assembly 3, which includes a bogie 302 and a steering wheel 301.

[0048] The climbing wheel 203 rotates around its own axis to realize the movement of the vehicle body 1. When the vehicle body 1 needs to turn, the bogie 302 or the steering wheel 301 rotates around the first axis to adjust the travel direction of the vehicle body 1. The solution in this embodiment can not only keep the storage surface of the vehicle body 1 in a horizontal state on the slope section, but also freely adjust the direction of the vehicle body 1 according to the travel needs, and the use flexibility is higher.

[0049] It should be noted that the steering assembly 3 can be used in conjunction with the climbing assembly 2 or can be used alone. For example, when the vehicle body 1 is traveling on a normal road, in order to facilitate turning, the bogie 302 can also be connected to the vehicle body 1. When on a horizontal road, the steering wheel 301 and the running wheel 101 are located in the same plane.

[0050] In some embodiments, see Figure 1 The bogie 302 includes a fixing member and a connecting member, the fixing member is detachably connected to the vehicle body 1; the connecting member is connected to the fixing member by rotation around a first axis, and the steering wheel 301 is connected to the connecting member by rotation around its own axis.

[0051] During normal driving, the steering wheel 301 rotates around its own axis. When turning is required, the connecting member rotates around the first axis, thereby realizing the rotation of the steering wheel 301 around the first axis and adjusting the traveling direction of the vehicle body 1.

[0052] Optionally, the fixing member is plug-connected, screw-connected or snap-connected to the vehicle body 1 .

[0054] In this embodiment, multiple support members 201 are provided to increase the connection points with the vehicle body 1, thereby improving the firmness and stability of the connection between the mounting frame and the vehicle body 1. In addition, each support member 201 is connected to a climbing wheel 203 to reduce the pressure of the vehicle body 1 on the road surface during the movement of the vehicle body 1. The reinforcement member 202 connects the multiple support members 201 to form an integral structure, thereby increasing the strength of the mounting frame.

[0055] In some embodiments, see Figure 1 The mounting frame is a telescopic member that telescopes in the up and down directions.

[0056] The mounting frame is a telescopic component, and the telescopic amount of the mounting frame can be adjusted according to the slope of the slope to ensure that the storage surface of the vehicle body 1 is in a horizontal plane, thereby improving the stability of the material on the vehicle body 1.

[0057] Optionally, the mounting bracket is a hydraulic or pneumatic telescopic member, or a manually adjustable telescopic rod.

[0058] In some embodiments, see Figure 1 and Figure 3 The car body 1 is provided with a first mounting hole, the bogie 302 includes a mounting piece 3021, a bearing 3022 and a bearing seat 3023, the mounting piece 3021 is arranged in the up and down direction, the steering wheel 301 is connected to the mounting piece 3021 for rotation around its own axis; the bearing 3022 is connected to the top of the mounting piece 3021; ​​the bearing seat 3023 is sleeved outside the bearing 3022, and the bearing seat 3023 has a second mounting hole 3024 adapted to the first mounting hole, and locking pieces are inserted in the first mounting hole and the second mounting hole 3024.

[0059] After the first mounting hole and the second mounting hole 3024 correspond to each other, the locking member is inserted into the first mounting hole and the second mounting hole 3024 to realize the detachable connection between the bearing seat 3023 and the vehicle body 1. When the traveling direction of the vehicle body 1 needs to be adjusted, the rotating wheel drives the mounting member 3021 to rotate with the up-down direction as the axis, and the bearing seat 3023 and the vehicle body 1 do not rotate at this time.

[0060] Optionally, the locking member is a threaded member or a clamping member.

[0061] In some embodiments, see Figure 1 The bogie 302 is a telescopic member and is telescopic in the up and down directions.

[0063] Optionally, the bogie 302 is a hydraulic or pneumatic telescopic member, or a manually adjustable telescopic rod.

[0064] Based on the same inventive concept, the utility model also provides a material transport device, which comprises any of the multifunctional material pushers described above, and further comprises a traction device 4 connected to the multifunctional material pusher.

[0065] The material transport device provided by the utility model adopts the above-mentioned multifunctional material pusher.

When the vehicle body 1 drives to the slope section, the driving wheel 101 is located at a higher position of the slope section, and the climbing wheel 203 is located at a lower position of the slope section. Since the height difference between the climbing wheel 203 and the driving wheel 101 levels the height difference formed by the slope, the storage surface of the vehicle body 1 continues to remain horizontal. The scheme in the utility model can determine whether to use the climbing component 2 according to the actual road conditions of the construction site, and the storage surface of the vehicle body 1 can be kept horizontal even on the slope section, avoiding the problem of material falling or the tilt of the vehicle body 1 causing the vehicle to overturn.

[0066] Optionally, the traction device 4 may be a tractor.

[0067] In some embodiments, see Figure 4 The traction device 4 includes a driver 401, a reel 402 and a traction rope 403. The reel 402 is connected to the driver 401, and the driver 401 drives the reel 402 to rotate around its own axis; one end of the traction rope 403 is connected to the reel 402, and the other end is connected to the vehicle body 1. The reel 402 rotates around its own axis to realize the retraction and release of the traction rope 403.

[0068] When the traction device 4 is needed, the traction rope 403 is connected to the vehicle body 1.
