Description

Technical Field

[0001] The utility model relates to the technical field of semi-trailers with adjustable sidewalls, in particular to a semi-trailer with conveniently adjustable sidewalls. Background Art

[0002] A semitrailer is a trailer with an axle placed behind the vehicle's center of gravity (when the vehicle is evenly loaded) and equipped with a coupling device that can transmit horizontal and vertical forces to the tractor. A semitrailer is generally a three-axle semitrailer, which is divided into many types, such as 11-meter warehouse semitrailer, 13-meter warehouse semitrailer, low-bed semitrailer, etc. It is a heavy-duty transport vehicle connected to the semitrailer head through a traction pin.

[0003] In a semi-trailer for transporting steel pipes, multiple groups of steel pipes are usually tied together by fixing ropes. Since the fixing ropes can only bind and fix the surfaces of the stacked steel pipes, when encountering bumpy roads during transportation, the steel pipes in the middle are easily affected by the bumps and collide with each other, resulting in looseness. The steel pipes in the middle are easily caused to fall off during long-distance transportation. In view of this, we propose a semi-trailer with an easily adjustable sideboard. Utility Model Content

[0004] The utility model aims to overcome the shortcomings of the prior art, meet practical needs, and provide a semi-trailer with conveniently adjustable side panels to solve the current technical problem that steel pipes are easily dropped when transported by fixed ropes.

[0005] In order to achieve the purpose of the utility model, the technical solution adopted by the utility model is: design a semi-trailer with conveniently adjustable sidewalls, comprising a box body with an upper surface opening, a bottom plate fixedly placed at the bottom of the box body, fixed rods fixedly placed on both sides of the box body, and a limited position assembly slidingly arranged on the surface of the fixed rod;

[0006] The limit assembly includes a fence with vertical grooves opened at both ends of the upper surface, the bottom end of the vertical groove is fixedly connected to a spring, the top end of the spring is fixedly placed with a push rod, and the center of the upper surface of the push rod is fixedly connected to a limit block;

[0007] A clamping assembly for placing steel pipes is placed on one side of the guardrail;

[0008] The clamping assembly includes a plurality of fixed rollers fixedly placed on one side of the guardrail, a female snap-in seat is fixedly connected to one side of the guardrail, a male snap-in seat is movably connected to the outer side of the female snap-in seat, a threaded column is connected to the outer end of the male snap-in seat, and the outer side of the threaded column is movably connected to the threaded groove on the back side of the fixed roller.

[0009] Preferably, an upper arc-shaped clamping block is fixedly connected to one end of the fixed roller, and a hydraulic cylinder is fixedly connected to the center of the lower surface of the upper arc-shaped clamping block.

[0010] Preferably, the telescopic end of the hydraulic cylinder is fixedly connected with a lower arc clamping block, and the upper arc clamping block and the lower arc clamping block are symmetrically semicircular and bent from the center to both sides, and the upper arc clamping block and the lower arc clamping block fit together to form a movable cavity.

[0011] Preferably, sliding grooves are provided on both sides of the guardrail, and the fixing rod is slidably connected to the guardrail through the sliding grooves.

[0012] Preferably, a plurality of limiting holes are formed at the lower end of the fixing rod, and the limiting block is clamped with the fixing rod through the limiting holes.

[0013] Preferably, the surface of the bottom plate is in the shape of a plurality of triangular protrusions, the lower end surface of the guardrail is slidably connected to the upper surface of the bottom plate, and at least one set of hooks are fixedly placed on both sides of the box body.

[0014] Compared with the prior art, the beneficial effects of the utility model are:

[0015] 1. This device can conveniently move the guardrail and fix its position by setting the limit block and the limit hole, so that the fixed roller is embedded in the inner wall of the steel pipe, and the other end of the steel pipe is against the side wall of the box body, so as to form a horizontal clamp for the steel pipe. In addition, after the steel pipe is stacked, the telescopic movement of the hydraulic cylinder can drive the lower arc clamping block to move downward and fit with the inner wall of the steel pipe. Through the longitudinal movement of the upper arc clamping block and the lower arc clamping block, a radial clamp is formed inside the steel pipe, which can improve the stability of the steel pipe during transportation.

[0016] 2. By setting the female and male snap-in seats, the fixed rollers can be flexibly disassembled when transporting different numbers of steel pipes, avoiding the inconvenience of repairing and replacing the component due to the integrated design, and reducing maintenance costs. By setting the triangular protrusion of the placement plate, the steel pipe can be staggered and placed in the triangular groove, so that both sides of the triangular groove can contact the surface of the steel pipe at the same time, increasing the contact points between the placement plate and the steel pipe, and making the bottom steel pipe more firmly placed. At the same time, by setting a plurality of limit holes, the position of the guardrail can be adjusted more flexibly, which is convenient for placing and fixing steel pipes of different lengths.

By setting the spring 402, the elasticity of the spring 402 can be used to drive the limiting block 404 to move up and down, thereby improving the flexibility of the position adjustment of the fence 401;

[0026] A clamping assembly 5 for placing steel pipes is placed on one side of the guardrail 401;

[0027] The clamping assembly 5 includes a plurality of fixed rollers 501 fixedly placed on one side of the fence 401, a female snap-in seat 405 is fixedly connected to one side of the fence 401, a male snap-in seat 406 is movably connected to the outer side of the female snap-in seat 405, a threaded column 407 is connected to the outer end of the male snap-in seat 406, and the outer side of the threaded column 407 is movably connected to the threaded groove on the back side of the fixed roller 501.

[0028] Specifically, one end of the fixed roller 501 is fixedly connected to an upper arc-shaped clamping block 502, a hydraulic cylinder 503 is fixedly connected to the center of the lower surface of the upper arc-shaped clamping block 502, and the telescopic end of the hydraulic cylinder 503 is fixedly connected to a lower arc-shaped clamping block 504. The upper arc-shaped clamping block 502 and the lower arc-shaped clamping block 504 are symmetrically semicircular and bent from the center to both sides, and the upper arc-shaped clamping block 502 and the lower arc-shaped clamping block 504 fit together up and down to form a movable cavity.

[0029] Furthermore, slide grooves are provided on both sides of the guardrail 401, and the fixing rod 3 is slidably connected to the guardrail 401 through the slide grooves. A plurality of limiting holes 301 are provided at the lower end of the fixing rod 3, and the limiting block 404 is clamped with the fixing rod 3 through the limiting holes 301. The surface of the bottom plate 2 is in the shape of a plurality of triangular protrusions, and the lower end surface of the guardrail 401 is slidably connected to the upper surface of the bottom plate 2. At least one group of hooks 6 are fixedly placed on both sides of the box body 1. By setting the limiting holes 301, the position of the guardrail 401 can be placed more flexibly, so that the guardrail 401 can place steel pipes of different lengths; the steel pipes can be staggered through the triangular protrusions of the bottom plate 2, so that the steel pipes can be placed in the triangular grooves and the two side surfaces of the triangular grooves can be used to form two contact points with the surface of the steel pipes to limit the bottom steel pipes, so that the overall stacking of the pipelines is more stable.
