Description

Technical Field

[0001] The utility model belongs to the technical field related to trackless flat cars, in particular to an explosion-proof omnidirectional trackless flat car. Background Art

[0002] Trackless flat cars, also known as trackless flatbed cars or trackless electric flat cars, are vehicles used for transporting materials across workshops. Compared to track flat cars, trackless flat cars are independent of tracks, achieving flexible and free operations, making the transportation of materials in factory sites and workshops faster and more convenient, saving time and reducing costs. However, they still have the following disadvantages in actual use:

[0003] During the operation of the trackless flat car, the goods are directly placed on the top of the flat car for transportation. However, the shapes of the goods in the factory are different. When the goods are placed on the flat car, some of the goods are cylindrical. During the movement of the flat car, there is a safety hazard that the goods may fall, affecting the safety of use.

[0004] During the operation of the trackless flat car, when it moves to the appropriate position, it needs to carry out loading and unloading operations of goods. During the operation, the flat car is directly set at the position for loading and unloading goods, and its rollers can still roll. The support stability of the flat car is not good enough, which is prone to safety hazards. Utility Model Content

[0005] The purpose of the utility model is to provide an explosion-proof omnidirectional trackless flat car. By arranging a trackless flat car body, a fixed frame, a movable cavity and a sponge strip, the problem that the trackless flat car has an insufficient restrictive effect on the cargo during operation and the supporting stability of the flat car is not good enough when loading and unloading cargo is solved.

[0006] In order to solve the above technical problems, the present invention is achieved through the following technical solutions:

[0007] The top of described supporting plate is fixed with the supporting plate of described supporting plate, and the top of described supporting plate is provided with movable slots equidistantly and parallel to the width direction of described supporting plate, and each movable slot is movably connected with a partition in each movable slot. The movable chamber is fixed on both ends of described supporting plate main body, and each movable chamber is fixed with a sponge bar on the side away from the trackless flat car main body. The lower part of described movable chamber is movably connected with a lifting bar, and the bottom of each lifting bar is fixed with a lifting plate, and the two lifting plates are symmetrically arranged with each other. When working, when power is generated by the trackless flat car main body, cargo in the fixed frame is transported, and cargo is supported in a suitable position by the support plate in the fixed frame, and an electric push rod is fixed therein through the movable chamber to drive the lifting bar to rise and fall, and the sponge bar provides an anti-collision effect for the trackless flat car main body when working.

[0008] Furthermore, a fixing opening is provided vertically through the center of the main body of the trackless flat car, and an explosion-proof battery is fixed in the fixing opening. The top surface height of the explosion-proof battery is lower than the top height of the main body of the trackless flat car. When the main body of the trackless flat car is working, the explosion-proof battery is fixed therein through the fixing opening, and the explosion-proof battery is used to supply energy to the main body of the trackless flat car.

[0009] Furthermore, openings are provided on both sides of the trackless flat car body, and a universal drive wheel is fixed in each of the openings. When the trackless flat car body is working, the universal drive wheel is fixed therein through the opening, and when the universal drive wheel works, the trackless flat car body is driven to move.

[0010] Furthermore, the bottom of the support plate is fixed to the top of the trackless flat car body, and the top surface height of the partition is higher than the top height of the fixed frame. When the support plate is working, it is fixed to the top of the trackless flat car to limit the position of the trackless flat car, and the space in the fixed frame is separated by the partition.

[0011] Furthermore, two parallel electric push rods are fixed in each of the active chambers, and piston rods are fixed to the telescopic ends of the two electric push rods. The bottom ends of the two piston rods in the same active chamber are fixed to the top of the lifting bar. When the active chamber is working, the piston rods are driven to rise and fall by the electric push rods, and the lifting bar is driven to rise and fall by the lifting of the piston rods.

[0012] Furthermore, a protective plate is fixed on the side of the sponge strip away from the active cavity, and the distance between the protective plate and the active cavity is greater than the distance the lifting plate extends out of the side of the active cavity. When the sponge strip is working, the edge of the sponge strip is protected by the protective plate to reduce damage to the protective plate.

[0013] The utility model has the following beneficial effects:

[0014] The utility model solves the problem that the trackless flat car has an insufficient restriction effect on the cargo during operation by arranging the trackless flat car body and the fixed frame. When working, the size of the cargo is determined, and the partitions on the movable grooves at different positions are immediately pulled out. After the cargo is well supported on the support plate, the corresponding structure is placed in a suitable position to restrict the position of the fixed frame. Then the universal driving wheel on the trackless flat car body can be started, and the trackless flat car body can be driven to move to the specified position by the universal driving wheel. After unloading, the operation is completed, so that the trackless flat car has a better restriction effect on the cargo during operation.

[0015] The utility model solves the problem of insufficient support stability of the trackless flat car when loading and unloading goods by arranging the trackless flat car body, the movable cavity and the sponge strip. When the trackless flat car body moves to a suitable position and needs to be loaded and unloaded, the electric push rod is started, and the electric push rod drives the piston rod to descend, and the piston rod descends, which drives the lifting bar to descend, and the lifting bar descends, which drives the lifting plate to descend until the lifting plate contacts the ground, and lifts the trackless flat car body until the universal drive wheel leaves the ground, so that the trackless flat car body is stably supported on the ground, and the support stability of the trackless flat car is better when loading and unloading goods.
