For ordinary technicians in this field, the specific meanings of the above terms in this embodiment can be understood according to specific circumstances.

[0032] In order to make the purpose, technical solution and advantages of the present invention more clear, the implementation mode of the present invention will be further described in detail below with reference to the accompanying drawings.

[0033] In the prior art, the material distribution vehicle 1 reciprocates along the length direction of the storage cabinet to evenly spread the material in the storage cabinet. The material distribution vehicle 1 is electrically connected to the power supply through a cable 2. Multiple clamping points on the cable 2 are fixed to the slide rail 3 through a clamp 18 respectively. The clamp 18 can slide along the slide rail 3 so that the cable 2 can slide back and forth on the slide rail 3 during the material distribution process to follow the movement of the material distribution vehicle 1. However, the cable 2 often breaks near the slide rail 3. The applicant has discovered that the main clamp 4 in the prior art (the clamp 18 closest to the material distribution vehicle 1 along the power transmission direction is the main clamp 4) is fixedly connected to the material distribution vehicle 1. When the material distribution vehicle 1 starts to run, it drives the main clamp 4 to start moving. The acceleration of the main clamp 4 when it starts to move is equal to the acceleration of the material distribution vehicle 1. Due to the effect of inertia, the acceleration of the cable 2 and other clamps 18 is much smaller than the acceleration of the main clamp 4. Therefore, the connection between the cable 2 and the main clamp 4 is subjected to a great impact force, which makes the cable 2 easy to be pulled and broken.

[0034] In order to solve the above technical problems, the embodiment of the utility model provides a cable fixing device for fixing the cable 2 of the cabinet distribution vehicle 1, such as Figure 1 and Figure 3 As shown, the cable fixing device comprises a slide rail 3, a plurality of clamps 18 and an elastic member 5. The slide rail 3 is arranged on one side of the storage cabinet, and the slide rail 3 extends along the length direction of the storage cabinet (such as Figure 1 and Figure 3 The slide rail 3 extends in the direction of the X-axis (shown in the middle). Specifically, the slide rail 3 is relatively stationary with the storage cabinet, and the slide rail 3 can be arranged on the storage cabinet or on the ground. The clamp 18 is used to clamp the cable 2. Each clamp 18 is arranged on the slide rail 3 in sequence along the extension direction of the slide rail 3 and can slide back and forth along the slide rail 3. Among them, the clamp 18 closest to the material distribution vehicle 1 along the power transmission direction is the main clamp 4. The elastic member 5 is arranged between the material distribution vehicle 1 and the main clamp 4, and the elastic member 5 is used to buffer the force applied by the material distribution vehicle 1 to the main clamp 4.

[0035] By adopting the above technical solution, the cable 2 is fixed on the slide rail 3 by the clamp 18, so that the cable 2 can expand and contract along the length direction of the storage cabinet when the material distribution vehicle 1 moves, so as to adapt to the reciprocating motion of the material distribution vehicle 1 and stably transmit power to the material distribution vehicle 1. Compared with the fixed connection between the clamp 18 and the material distribution vehicle 1 in the prior art, the embodiment of the present application can buffer the force applied to the clamp 18 when the material distribution vehicle 1 starts by arranging an elastic member 5 between the material distribution vehicle 1 and the bracket of the clamp 18, so that the clamp 18 can gradually start to move, thereby reducing the acceleration of the clamp, and avoiding the instantaneous acceleration of the clamp 18 being too large and pulling the cable 2 to break.

[0036] Furthermore, if Figure 1 As shown, the cable 2 is provided with a plurality of clamping points arranged at intervals, and the clamp 18 is connected to the cable 2 at the clamping points, and the number of the clamping points and the clamp 18 is equal and one-to-one corresponding. The clamp 18 can prevent the cable 2 from dragging on the ground and winding by clamping and fixing the clamping points on the cable 2, and realize the expansion and contraction of the cable 2 by sliding along the slide rail 3. Specifically, the length of the cable 2 between two adjacent clamping points is 2-3 meters. The length setting of the cable 2 between two adjacent clamping points depends on the unit length weight of the cable 2 and the height of the slide rail 3 from the ground. When the unit length weight of the cable 2 is large, it is necessary to shorten the cable length between the clamping points, such as 2 meters, to reduce the force of the clamp. On the contrary, when the unit length weight of the cable 2 is small, the distance between the two adjacent clamping points can be appropriately increased (such as 3 meters). When the slide rail 3 is more than 2 meters from the ground, the length of the cable 2 between the two adjacent clamping points can be extended to 3 meters, and when the slide rail 3 is less than 2 meters from the ground, the length of the cable 2 between the two adjacent clamping points can be shortened to 2 meters.

[0037] Furthermore, if Figure 1 and Figure 3 As shown, the fixture 18 is located below the slide rail 3, and a slide groove 6 is provided inside the slide rail 3 along the extension direction of the slide rail 3 (as shown in FIG. Figure 1 and Figure 2 As shown in FIG. 1 ), the bottom of the slide rail 3 is provided with a clearance groove 7 arranged along the extension direction of the slide rail 3, and the clearance groove 7 is connected to the slide groove 6; the clamp 18 is provided with a sliding mechanism 8, and the sliding mechanism 8 is at least partially arranged in the slide groove 6, and the sliding mechanism 8 can slide back and forth in the slide groove 6 along the length direction of the slide groove 6. Specifically, an opening is provided at the end of the slide rail 3. When installing the fixing device, the upper part of the sliding mechanism 8 is installed into the slide groove 6 from the end of the slide rail 3. The end opening of the slide rail 3 is in contact with the cross section of the slide rail 3 (as shown in FIG. 1 ). Figure 2 As shown in Figure 2, the shape is the same as Figure 2 As shown, the width of the slide groove 6 is greater than the width of the clearance groove 7 , and a step is formed between the slide groove 6 and the clearance groove 7 , which can prevent the sliding mechanism 8 from escaping from the slide groove 6 .

[0038] Furthermore, the sliding mechanism 8 includes at least two rollers 9, each of which is disposed in the slide groove 6 and in contact with the bottom surface of the slide groove 6, and the rollers 9 can roll on the bottom surface of the slide groove 6 along the length direction of the slide groove 6. Specifically, the rollers 9 are bearings, which are used to reduce the friction between the sliding mechanism 8 and the slide groove 6, so as to reduce the resistance of the main clamp 4 to drag the cable 2 to move, and prevent the cable 2 from being pulled and broken.

[0039] Furthermore, if Figure 2 and Figure 3As shown, the clamp 18 includes a main frame 10, a clamping plate 11, a bolt 12 and a connecting shaft 15. The upper end of the main frame 10 extends into the slide groove 6 through the clearance groove 7, and the lower end of the main frame 10 is located outside the slide groove 6. The lower surface of the main frame 10 is provided with a plurality of threaded holes 13 extending in the vertical direction. The clamping plate 11 is provided with a plurality of through holes 14 extending in the vertical direction, and the cable 2 is arranged between the main frame 10 and the clamping plate 11. The bolt 12 passes through the through hole 14 and is threadedly connected with the threaded hole 13. When the bolt 12 is tightened, the clamping plate 11 and the main frame 10 can clamp the cable 2. The connecting shaft 15 is arranged above the main frame 10, the connecting shaft 15 is located in the slide groove 6 and extends along the width direction of the slide groove 6, and the number of rollers 9 is two, and the two rollers 9 are respectively sleeved on the two ends of the connecting shaft 15 and can rotate around the connecting shaft 15. Specifically, the cable 2 is a flat cable 2 , which facilitates the clamping plate 11 and the main frame 10 to clamp the cable 2 .

[0040] Furthermore, if Figure 3 As shown, a buffer frame 16 is provided on the fabric trolley 1, and the buffer frame 16 includes two connecting plates 17 spaced apart along the length direction of the fabric trolley 1, and the main frame 10 is provided between the two connecting plates 17, and an elastic member 5 is provided between each connecting plate 17 and the main frame 10. Specifically, the elastic member 5 is a tension spring, one end of which is detachably connected to the connecting plate 17, and the other end is detachably connected to the main frame 10. Exemplarily, connecting holes are provided on the main frame and the connecting plate, and hooks are provided on both ends of the tension spring, and the two hooks are respectively connected to the connecting holes on the main board and the connecting plate.
