Description

Technical Field

[0001] This invention belongs to the technical field of adjustable end frame fixing devices, and particularly relates to an adjustable end frame fixing device that can be used for the transportation of medium and large-sized goods. Background Technology

[0002] In current freight transportation, equipment and goods are usually secured by binding, which may cause them to tilt during transportation, posing certain safety hazards and failing to meet the needs of transporting goods of different lengths. Summary of the Invention

[0003] In view of the shortcomings of the existing technology, the purpose of this invention is to provide an adjustable end frame fixing device that can be used for the adjustment and fixing of cylindrical goods of different lengths and sizes during transportation. It has the advantages of simple structure, low cost, and adaptability to the transportation of goods of different lengths.

[0004] To achieve the above objectives, the technical solution adopted by the present invention is as follows:

[0005] An adjustable end frame fixing device includes an end frame, a front-to-back adjustment device, a roller assembly, a roller guide rail assembly, and a fixed tail frame. The roller assembly and the front-to-back adjustment device are mounted on the end frame, and the roller guide rail assembly is mounted on the fixed tail frame. The end frame and the fixed tail frame are connected by the front-to-back adjustment device.

[0006] Furthermore, the front and rear adjustment device consists of an arc-shaped base, a connecting screw, an adjustment handle, a washer, and a fixing nut.

[0007] Furthermore, the connecting screw is spiral-shaped, and the adjustment handle is set on the front and rear adjustment device. The distance between the end frame and the fixed tail frame is controlled by adjusting the handle.

[0008] Furthermore, the connecting screw is mounted on the arc-shaped base, which is welded to the end frame.

[0009] Furthermore, the connecting screw is installed in sequence with the adjusting handle, washer, fixed tail frame, washer, and fixing nut. The length of the connecting screw is adjusted back and forth by adjusting the thread of the connecting screw, and the fixing nut controls the rotation of the adjusting handle.

[0010] Furthermore, the arc-shaped base and the connecting screw are assembled and connected in a hemispherical shape.

[0011] Furthermore, the roller assembly includes a roller base and a roller, with the roller mounted on the roller base.

[0012] Furthermore, the roller guide rail assembly includes roller guide rails, adjusting pads, and reinforcing base plates, with the reinforcing base plates welded to the bottom and left and right sides of the fixed tail frame.

[0013] Furthermore, the roller guide rails are U-shaped and can be detachably mounted on the fixed tail frame using bolts and adjusting pads.

[0014] Furthermore, the end frame and the fixed tail frame are adjusted by rolling using rollers.

[0015] The advantages of this invention are as follows: by setting an adjustment handle, the distance between the end frame and the fixed tail frame can be quickly adjusted; by setting the shape of the roller guide rail to be "U", the roller does not leave the roller guide rail while rolling, avoiding the possibility of falling off; by setting a fixing nut, the adjustment handle can be controlled.

[0016] Using the adjustable end frame fixing device disclosed in this utility model, medium and large-sized goods can be transported, achieving convenient fixing while having an adjustable function. In particular, it can adapt to changes in the length of the goods and has the advantages of simple structure and low cost. Attached Figure Description

Detailed Implementation

[0024] To make the objectives, technical solutions, and advantages of this application clearer, the following detailed description is provided in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the scope of this application.

[0025] like Figure 1 and Figure 4 As shown, the present invention discloses an adjustable end frame fixing device, including an end frame 10, a roller assembly 20, a roller guide rail assembly 30, a front and rear adjustment device 40, and a fixed tail frame 50. The roller assembly 20 and the front and rear adjustment device 40 are welded to the end frame 10, and the roller guide rail assembly 30 is welded to the fixed tail frame 50.

[0026] like Figure 1 , Figure 4 and Figure 5 As shown, the front and rear adjustment device includes an arc-shaped base 41, a connecting screw 42, an adjusting handle 43, a washer 44, and a fixing nut 45. The connecting screw 42 is installed in the arc-shaped base 41, and the arc-shaped base 41 is welded to the end frame 10. The adjusting handle 43, washer 44, fixing end frame 50, and fixing nut 45 are screwed together in sequence by the connecting screw 42, and the front and rear adjustment is performed by the threads on the screw.

[0027] Furthermore, the end frame 10 is connected to the fixed tail frame 50 via a connecting screw 42 and a circular hole. The end frame 10 is adjusted forward and backward in the X direction via the adjusting handle 43 of the front-to-back adjusting device 40 and the fixing nut 45. The distance between the end frame 10 and the fixed tail frame 50 is controlled by the adjusting handle 43. The roller assembly 20 and the roller guide rail assembly 30 form limits in the Y and Z directions, and the rollers roll forward and backward in the X direction.

[0028] like Figures 1 to 3 As shown, the roller assembly 20 consists of a roller seat 21 and a roller 22. The roller seat 21 is welded to the bottom and left and right sides of the end frame 10. The roller guide rail assembly 30 includes a roller guide rail 31, an adjusting pad 32, and a reinforcing base plate 33. The reinforcing base plate 33 is welded to the bottom and left and right sides of the fixed tail frame 50.

[0029] The working process of using the adjustable end frame fixing device disclosed in this invention to fix large goods during transportation is as follows:

[0030] S1. Remove the fixing nut 45 and washer 44 to allow the adjusting handle 43 to rotate.

[0031] S2. Rotate the adjusting handle 43 on this device, and the roller 22 moves on the roller guide rail 31, thereby achieving the purpose of separating the end frame 10 from the fixed tail frame 50. When the end frame 10 and the fixed tail frame 50 move relative to each other to the required distance, stop rotating the adjusting handle 43 and put the medium and large-sized goods to be transported into this device.

[0032] S3. Rotate the adjusting handle 43 of this device in the opposite direction. The roller 22 moves in the opposite direction on the roller guide rail 31. The distance between the end frame 10 and the fixed tail frame 50 is shortened. After the end frame 10 and the fixed tail frame 50 come into contact with the goods to be transported, stop rotating the adjusting handle 43.

[0033] S4. After inserting the washer 44 into the end of the connecting screw 42 that is close to the fixed tail frame 50, use the fixing nut 45 to install it on the connecting screw 42 and tighten it.

[0034] S5. Repeat step S4 above to tighten all the connecting screws 42 on this device with nuts 45.

[0035] As can be seen from the above embodiments, the present invention provides an adjustable end frame fixing device that can be applied to the fixing of medium and large cargo transportation. It has the advantages of simple structure, low cost, and adaptability to the transportation of cargo of different lengths.
