Description

Technical Field

[0001] The utility model relates to the technical field of transportation tools, in particular to a medium- and low-speed magnetic levitation transportation engineering material transportation flatbed vehicle. Background Art

[0002] During the construction of urban rail transit projects, the main materials required for project construction are heavy and cannot be carried for a long time by manpower, so flatbed trucks should be made for material transportation during the construction process. Different from the I-shaped rails used in conventional urban rail transit, medium and low-speed maglev transit tracks use F-shaped rails (including F-shaped steel, aluminum induction plates and fastening bolts). Due to the different structures of F-shaped rails and I-shaped rails, the flatbed trucks used in conventional urban rail transit construction cannot be used in medium and low-speed maglev transit projects. Based on this background, this plan develops and designs a transport flatbed truck used in medium and low-speed maglev transit projects for material transportation. Utility Model Content

[0003] Based on the above description, the utility model provides a medium- and low-speed maglev transportation engineering material transport flatbed vehicle to solve the problem that there is no transport flatbed vehicle for medium- and low-speed maglev tracks in the prior art.

[0004] The technical solution of the utility model to solve the above technical problems is as follows:

[0005] A medium- and low-speed magnetic levitation transportation engineering material transport flatbed vehicle, comprising:

[0006] Chassis;

[0007] Rollers are arranged at the bottom of the four corners of the chassis;

[0008] The guide wheels are arranged on both sides of the chassis and are respectively in contact with the F rails.

[0009] On the basis of the above technical solution, the present invention can also be improved as follows.

[0010] Furthermore, a brake assembly is provided on the roller, and the brake assembly includes a brake rod and a rebound member. The brake rod is hingedly arranged at the bottom of the chassis, and the brake rod is frictionally braked against the roller under the action of pressing. The rebound member is connected to the end of the brake rod and provides a force to drive the brake rod to reset.

[0011] Furthermore, a connecting rod is connected to the chassis, and the guide wheel is vertically arranged at the bottom of the connecting rod, and the guide wheel abuts against the vertical inner wall of the F rail.

[0012] Furthermore, the chassis is provided with reinforcing ribs connected to the connecting rods.

[0013] Furthermore, at least two groups of guide wheels are arranged on each side of the chassis.

[0014] Furthermore, the chassis is a frame structure.

[0015] Furthermore, the roller and the guide wheel are made of nylon.

[0016] Furthermore, a traction rope hanging ring is arranged on the chassis.

[0017] Compared with the prior art, the technical solution of this application has the following beneficial technical effects:

[0018] 1. After adopting this technical solution, the construction intensity of personnel is reduced, the construction efficiency is improved, and the possibility of manual damage to materials during construction and transportation is reduced, thus ensuring the quality of materials.

[0019] 2. The flatbed car is equipped with nylon rollers with brakes, which will not cause damage to the F rail. It has a heavy load-bearing capacity and can provide effective braking.

It should also be understood that the terms "include / comprise" or "have" etc. specify the presence of stated features, wholes, steps, operations, components, parts or combinations thereof, but do not exclude the possibility of the presence or addition of one or more other features, wholes, steps, operations, components, parts or combinations thereof.

[0032] like Figure 1 , Figure 2 A medium- and low-speed maglev transportation engineering material transport flatbed shown in the figure includes a chassis 1, and rollers 2 and guide wheels 3 are arranged at the bottom of the chassis 1. The chassis 1 adopts a frame structure, which is a rectangular frame formed by welding transverse and longitudinal materials. It has a solid structure and light weight. Pads can be laid on it to cover the gaps as needed. Rollers 2 are respectively arranged at the bottom of the four corners of the chassis 1, and steel plates are welded at the bottom of the four corners of the chassis 1. Sleeves are welded on the steel plates, and the outer wall of the sleeves is welded to the flatbed frame to fix the steel plates to the chassis 1. The guide wheels 3 are used to guide the steering, and are respectively arranged on both sides of the chassis 1, and respectively abut against the F rails.

[0033] A brake assembly is provided on the roller 2, and the brake assembly can be provided at the front roller 2 or the rear roller 2 or all the rollers 2. The brake assembly includes a brake rod 4 and a rebound member. The brake rod 4 is hingedly provided at the bottom of the chassis 1, and one end of the rod body of the brake rod 4 extends out of the chassis 1 for manual pressing or stepping. Under the pressing action, the bottom of the brake rod 4 fits against the roller 2 to form a friction brake. The rebound member is connected to the other end of the brake rod 4 and provides a force to drive the brake rod 4 to reset, that is, in the braking state, the end of the brake rod 4 presses the rebound member, and after the force pressing the brake rod 4 is lost, the brake rod 4 is reset under the action of the rebound member.

[0034] Specifically, the chassis 1 is welded with a connecting rod 5, and the guide wheel 3 is vertically arranged at the bottom of the connecting rod 5. The guide wheel 3 abuts against the vertical inner wall of the F rail, and the guide wheels 3 on both sides abut against the vertical inner walls of the F rails on both sides, that is, the guide wheel 3 is stuck between the F rails on both sides, and the roller 2 rolls on the F rails. The guide wheel 3 keeps the chassis 1 moving between the F rails to avoid separation. Correspondingly, the chassis 1 is provided with a reinforcing rib 6 welded to the connecting rod 5.

[0035] Preferably, at least two groups of guide wheels 3 are provided on each side of the chassis 1, and the front and rear four groups of guide wheels 3 form a rectangular frame, which effectively fixes the chassis 1 between the F rails.

[0036] Specifically, the roller 2 and the guide wheel 3 are made of nylon. The roller 2 is connected to the chassis 1 by bolts, which is convenient for replacing the wheel after it is damaged. The chassis 1 is provided with a traction rope hanging ring 7 at the front and rear to tow the flatbed truck.
