Description

Technical Field

[0001] The utility model belongs to the technical field of electric flat car protection, in particular to a safe and anti-collision electric flat car. Background Art

[0002] Electric flat car, also known as electric flatbed car, cross-car, electric rail car, level car, trolley, etc., is a heavy-duty cargo transport vehicle within the factory. This type of vehicle has the characteristics of simple structure, easy use, large carrying capacity, not afraid of dirt or smashing, easy maintenance, long service life, etc. Due to its convenience, sturdiness, economy, practicality, easy cleaning and many other advantages, it has become the preferred means of transportation for frequent short-distance fixed-point transportation of heavy objects within the factory building of the enterprise and between factories. The existing electric flat cars are mainly divided into rail electric flat cars and trackless electric flat cars. Most of the existing electric flat car bodies 1 are equipped with simple buffers 11 at the front and rear ends, as shown in the attached manual. Figure 1 When a vehicle collides during operation, the buffer will play a buffering role after touching the obstacle, and the vehicle body will be protected by damaging the buffer. This method not only has poor safety and reliability, but also has problems such as high maintenance cost and large waste of resources; in addition, as the authorization announcement number: CN206826579U, the patent name is: a utility model patent for a buffer-type motor vehicle bumper, which discloses another buffer-type bumper. The buffer plate 2 is guided by the telescopic rod 3 and the guide sleeve 4. The buffer plate 2 can only move along the direction of movement of the telescopic rod 3 (guide sleeve 4). The buffer plate 2 cannot play a buffering role after being subjected to a lateral impact force. Therefore, the above two buffer mechanisms require that the obstacle is in the positive direction of the electric flat car to play a buffering effect. In other words, if the obstacle is not in front of the buffer, the buffer will not touch the obstacle or touch the obstacle at an angle, which will damage the obstacle and fail to protect the electric flat car. Therefore, in the prior art, the electric flat car buffer is limited by the impact direction of the obstacle when in use, and cannot play a good protective role for the electric flat car. Utility Model Content

[0003] The utility model aims to solve the technical problem that the existing protection device for electric flat cars has a poor protection effect on electric flat cars, and provides a safe and anti-collision electric flat car, which includes an electric flat car body and a traveling mechanism assembled on the electric flat car body. The traveling mechanism includes traveling wheels rotatably assembled on the electric flat car body. A transmission shaft is arranged between the traveling wheels. A traveling motor and a speed reducer are also arranged on the electric flat car body. The power output shaft of the traveling motor is in transmission connection with the transmission shaft. A plurality of buffer devices for buffering are arranged around the electric flat car body. The buffer device includes a support frame detachably fixed on the electric flat car body and a baffle arranged outside the support frame. A plurality of buffer mechanisms are arranged between the baffle and the support frame. The buffer mechanism includes an upper sleeve. A support rod is fixed at the top end of the upper sleeve. A hinge seat is fixed on the baffle above the support rod. The upper end of the support rod is hinged to the hinge seat. The lower end of the upper sleeve is sleeved with a lower sleeve. A guide rod is fixed at the inner top end of the upper sleeve. The upper end of the lower sleeve is slidably connected to the guide rod. A first compression spring is arranged between the top end of the lower sleeve and the top end of the upper sleeve. The bottom end of the lower sleeve is fixed with a "T"-shaped slider. A chute corresponding to the slider is opened on the support frame below the lower sleeve. The cross section of the chute is "convex"-shaped, and the slider can be slidably assembled in the chute. Second compression springs are arranged in the chute on both sides of the slider. The two second compression springs are symmetrically arranged. The arrangement of the chute, the slider and the second compression springs enables the second compression springs to play a buffering role after the baffle obliquely collides with an obstacle, which is suitable for the electric flat car to obliquely hit an obstacle. When the electric flat car body is moving, after the baffle touches an obstacle, the baffle pushes the support rod downward, and the first compression spring in the upper sleeve is compressed. Under the reaction of the first compression spring, a buffering effect is achieved. Both the support frame and the baffle include a horizontal part and inclined parts at both ends of the horizontal part. At least two buffer mechanisms are arranged between the inclined part of the baffle and the support frame. The buffer mechanisms are inclined and perpendicular to the inclined part. The horizontal part and the inclined part of the baffle can be suitable for different impact angles between the baffle and the obstacle, and the buffer mechanisms between the baffle and the support frame can all play a buffering role. Two symmetrically arranged guide holes are opened on the upper sleeve. The two guide holes are respectively located on the opposite sides of the upper sleeve, and the guide holes are arranged along the length direction of the upper sleeve. An assembly hole corresponding to the guide hole is opened on the lower sleeve. A guide bolt is arranged in the guide hole, and both ends of the guide bolt extend out of the upper sleeve.

[0005] Preferably, a limiting plate is detachably fixed at the bottom end of the guide rod.

[0006] The adoption of the above scheme has the following advantages:

[0007] The buffer mechanism is provided. When the baffle is impacted, the baffle pushes the upper sleeve through the support rod to compress the first compression spring. Under the action of the first compression spring, it plays a buffering role for the electric flat car body, avoiding damage to the electric flat car after the electric flat car body directly impacts an obstacle; the baffle and the support frame are provided with a horizontal part and an inclined part, which can be applicable to the situation where the electric balance car impacts an obstacle at different angles, making it more convenient to use; the setting of the chute, slider and the second compression spring, after the baffle obliquely collides with an obstacle, the second compression spring plays a buffering role, which is applicable to the electric flat car obliquely hitting an obstacle.

The upper end of the support rod 42 is hinged to the hinge seat 323. The lower end of the upper sleeve 41 is sleeved with a lower sleeve 43. A guide rod 441 is fixed at the inner top end of the upper sleeve 41. The upper end of the lower sleeve 43 is slidably connected to the guide rod 441. A first compression spring 44 is provided between the top end of the lower sleeve 43 and the top end of the upper sleeve 41. A "T"-shaped slider 48 is fixed at the bottom end of the lower sleeve 43. A chute 47 corresponding to the slider 48 is provided on the support frame 31 below the lower sleeve 43. The cross section of the chute 47 is in the shape of a "convex". The slider 48 can be slidably assembled in the chute 47. Second compression springs 49 are provided in the chute 47 on both sides of the slider 48. The two second compression springs 49 are symmetrically arranged. The arrangement of the chute 47, the slider 48 and the second compression spring 49 enables the second compression spring 49 to play a buffering role when the baffle 32 obliquely collides with an obstacle, which is applicable to the electric flat car body 1 obliquely hitting an obstacle. When the electric flat car body 1 is moving and the baffle 32 touches an obstacle, the baffle 32 pushes the support rod 42 downward, and the first compression spring 44 in the upper sleeve 41 is compressed. Under the reaction of the first compression spring 44, a buffering effect is achieved. Both the support frame 31 and the baffle 32 include a horizontal portion 321 and inclined portions 322 at both ends of the horizontal portion 321. At least two buffer mechanisms 4 are provided between the inclined portion 322 of the baffle 32 and the support frame 31. The buffer mechanisms 4 are obliquely arranged and perpendicular to the inclined portion 322.

An assembly hole (not shown in the specification drawings) corresponding to the guide hole 45 is provided on the lower sleeve 43. A guide bolt 46 is provided in the guide hole 45, and both ends of the guide bolt 46 extend out of the upper sleeve 41.

[0015] Preferably, a plurality of support columns 34 are fixed on the support frame 31. A fixing seat 33 is provided at the end of the support column 34, and the fixing seat 33 is detachably fixed on the electric flat car body 1.

[0016] Preferably, a limiting plate 442 is detachably fixed to the bottom end of the guide rod 441.

[0017] Usage process:

[0018] When the present utility model is in use, when the electric flat car body 1 encounters an obstacle during walking, the baffle 32 touches the obstacle. The baffle 32 pushes the upper sleeve 41 towards the lower sleeve 43 through the support rod 42. At this time, the first compression spring 44 in the upper sleeve 41 is compressed. Under the action of the reaction force of the first compression spring 44, a buffering effect is achieved, which plays a protective role for both the obstacle and the electric flat car body 1. When the electric flat car body 1 hits the obstacle obliquely, the baffle 32 first touches the obstacle. At this time, the slider 48 at the lower end of the lower sleeve 43 slides along the chute 47, and the two second compression springs 49 in the chute 47 play a buffering role for the slider 48. At the same time, the first compression spring 44 will also be compressed accordingly, and the first compression spring 44 can also play a buffering role.
