Description

Technical Field

[0001] This utility model relates to the field of auxiliary technology for transport vehicle compartments, specifically a telescopic transport vehicle compartment tensioning and fixing device. Background Technology

[0002] During cargo transportation, the inertial forces generated when a vehicle starts, brakes, and turns can cause relative displacement between the cargo and the vehicle compartment.

[0003] Especially in long-distance transportation or in complex road conditions, such displacement may cause cargo to stack and tilt, or the side panels of the carriage to be squeezed. In extreme cases, it may cause deformation of the carriage frame, failure of door locks, or even traffic safety accidents such as cargo falling. Therefore, there is an urgent need for a telescopic transport vehicle carriage tensioning and fixing device to solve the above problems. Utility Model Content

[0004] In order to overcome the above-mentioned technical problems, the purpose of this utility model is to provide a retractable transport vehicle compartment tensioning and fixing device to solve the problems mentioned in the background art, especially in long-distance transportation or complex road conditions, where such displacement may cause cargo stacking to tilt, squeezing the side panels of the compartment, etc., and in extreme cases, may cause deformation of the compartment frame, failure of door locks, or even traffic safety accidents such as cargo falling.

[0005] This utility model provides the following technical solution: a retractable transport vehicle compartment tensioning and fixing device, including several Y-axis mechanisms, wherein the Y-axis mechanism includes a limiting rod and a symmetrical buckle, and the whole is U-shaped, and is fastened to the Y-axis of the compartment;

[0006] In addition, the threaded rod located at the end of the buckle connection and the first thread welded to the end of the limit rod connection, and the threaded rod and the first thread engage and limit the movement, adjusting the length of the threaded rod embedded in the limit rod chamber;

[0007] It also includes an X-axis mechanism, which is attached to the X-axis of the carriage.

[0008] To achieve the above technical solution, a U-shape is formed by a buckle, a threaded rod, and a limiting rod, which is inverted and fastened to the Y-axis at the top of the carriage. This ensures the safe fixation of the carriage during transportation, increases the lateral support stability of the vehicle, and prevents the carriage guardrail from suddenly deforming under stress during vehicle operation. At the same time, the threaded rod can be screwed into and out of the first thread, thereby changing the exposed length of the threaded rod, making this device suitable for carriages of different widths.

[0009] As a further improvement to this utility model, the buckle and the threaded rod are connected by a pivot rod.

[0010] By implementing the above technical solution, the rotating shaft can adapt well to changes in the carriage baffle, resist deformation caused by long-term use of the carriage, and can be easily adjusted and fixed.

[0011] As a further improvement to this utility model, an adjustment ring for the steel pipe to pass through is welded onto the limiting rod.

[0012] To achieve the above technical solution, the welding adjustment ring is rotated by bending the steel pipe, thereby adjusting the angle of the buckle and making it perpendicular to the carriage baffle.

[0013] As a further improvement to this utility model, a second thread is screwed into the threaded rod and is positioned in contact with and limited by the first thread.

[0014] To achieve the above technical solution, the first thread is attached to the first thread, and the first thread is squeezed and limited.

[0015] As a further improvement to this utility model, the first thread is a trapezoidal thread.

[0016] The above technical solution makes the first thread less likely to come loose accidentally.

[0017] As a further improvement to this utility model, the limiting rod is divided into two sections, which are connected and fixed by a connecting sleeve.

[0018] With the above technical solution implemented, users can subsequently extend and weld other accessories at the connecting sleeve.

[0019] As a further improvement to this utility model, the X-axis mechanism includes a first bending frame and a second bending frame that are symmetrically arranged and fixed by a connecting tube. The whole structure is U-shaped and is fastened to the X-axis of the carriage.

[0020] To achieve the above technical solution, the X-axis of the carriage is assisted in fastening.

[0021] As a further improvement to this utility model, the first bending frame and the second bending frame are fully welded together from galvanized steel pipe corner frames and 980 high-strength steel or 40cr high-strength alloy straight rods.

[0022] The above technical solution ensures the overall strength and tensile strength of the first bending frame and the second bending frame.

[0023] The technical effects and advantages of this utility model are as follows:

[0024] 1. This utility model uses a buckle, a threaded rod, and a limiting rod to form a U-shape, which is inverted and fastened to the Y-axis at the top of the carriage, so that the carriage is safely fixed during transportation, increasing the lateral support stability of the vehicle and preventing the carriage guardrail from being suddenly deformed by force during the vehicle's operation.

[0025] 2. The threaded rod of this utility model can be screwed into and out of the first thread, thereby changing the exposed length of the threaded rod, making this device suitable for carriages of different widths. Attached Figure Description

The number of Y-axis mechanisms 100 is selected according to the length of the vehicle, and they are evenly fastened to the top of the carriage in an inverted U-shape.

[0036] The buckle 110 is provided with a threaded rod 111 at the connecting end (movably connected to the buckle 110 via a rotating shaft rod), and a second threaded thread 115 is screwed into the threaded rod 111 (which is in contact with the first threaded thread 113 to form a mutual compression limit).

[0037] The first thread 113 (trapezoidal thread structure) is welded to the end of the limiting rod 112. The threaded rod 111 engages with the first thread 113 for limiting. The extension and retraction can be adjusted by adjusting the length of the threaded rod 111 screwed into the cavity of the limiting rod 112. The limiting rod 112 is divided into two sections (fixed by connecting sleeve 114, which facilitates the subsequent welding of other hanging tools at the connecting sleeve 114). The surface of the limiting rod 112 is welded with an adjustment ring 116 (inner diameter 20-25mm, for the auxiliary steel pipe to pass through).
