Description

Technical Field

[0001] This utility model belongs to the field of construction transportation equipment, and specifically relates to a trolley that assists in the movement of tubular objects. Background Technology

[0002] During the construction and transportation of tubular objects (such as submarine cables, guy wires, steel cables, steel pipe piles, and pipelines), the direct contact between the tubular objects and the ground can easily lead to damage due to ground roughness, friction during traction, or improper operation. Once the surface of the tubular object is damaged, it may not only affect its insulation / protection performance and reduce its service life, but may also seriously affect the quality of the tubular object and even lead to safety accidents. Utility Model Content

[0003] The present invention aims to provide a trolley to assist in the movement of tubular objects, so as to avoid damage to the tubular objects during construction and transportation.

[0004] The present invention provides a trolley for assisting the movement of a tubular object, comprising a bracket and casters mounted on the bottom of the bracket; an arc-shaped plate adapted to the tubular object is fixedly connected to the bracket, and a protective pad is provided on the side of the arc-shaped plate away from the bracket.

[0005] The beneficial effects of this solution are as follows: By setting up the curved plate, tubular objects can be placed on the curved plate to prevent them from detaching from the sides of the plate; since there is a protective pad on the curved plate, the tubular object is in direct contact with the protective pad, which can protect the tubular object from damage during transportation and provide a certain buffering effect to reduce the impact caused by uneven roads or vibrations.

[0006] Furthermore, the protective pad has clips on both sides for engaging with the curved plate. These clips allow for easy installation and removal of the protective pad, facilitating replacement or cleaning and improving the practicality and ease of maintenance of the trolley.

[0007] Furthermore, the outer wall of the arc-shaped plate is provided with threaded holes, and the buckle is provided with connecting holes. A first screw that mates with the threaded holes is installed in the connecting holes. Through the cooperation of the threaded holes and the first screw, the protective pad can be firmly fixed to the arc-shaped plate, ensuring that the protective pad will not fall off or shift during transportation, thus providing stable protection for tubular objects.

[0008] Furthermore, a fixing rope is fixedly connected to the bracket, and multiple through holes for the fixing rope to pass through are provided on both sides of the arc-shaped plate and the protective pad. The multiple through holes are arranged sequentially from bottom to top on the arc-shaped plate and the protective pad. The design of the fixing rope and through holes allows the trolley to adapt to tubular objects of different diameters. By adjusting the position of the fixing rope in the through holes, the tubular object can be firmly fixed, preventing it from slipping or falling off during transportation.

[0009] Furthermore, the bracket is also equipped with a fixing mechanism for securing the fixing rope. The fixing mechanism includes a fixing block with a horizontally arranged clearance hole for the fixing rope to pass through. The clearance hole penetrates the fixing block. The fixing block has multiple sets of holes, including guide holes and limiting holes arranged sequentially from top to bottom. The guide holes and limiting holes are coaxial and interconnected. The diameter of the guide hole is smaller than the diameter of the limiting hole. The limiting hole communicates with the clearance hole. A guide rod is vertically slidably connected within the guide hole. One end of the guide rod extends into the limiting hole and is fixedly connected to a fixing ball. A spring is sleeved on the guide rod, with one end of the spring abutting against the fixing ball and the other end abutting against the side wall at the top of the limiting hole. This fixing mechanism design allows for easy fixing and release of the fixing rope, improving the ease of operation of the trolley. Through the cooperation of the spring and the fixed ball, the fixed ball can fix the fixed rope inside the clearance hole. When the tubular object is in an inclined state and part of its outer wall is separated from the protective pad, the fixed rope is pulled upward by the force, which in turn acts on the fixed ball and the spring, so that the fixed rope can be properly released, avoiding the fixed rope from being broken or the trolley being pulled up.

[0010] Furthermore, multiple guide rods are fixedly connected to the same fixing rod. The design of the fixing rod allows multiple guide rods to be operated simultaneously. When the fixing rope needs to pass through the clearance hole, multiple guide rods can be lifted at once by the fixing rod, improving the convenience and efficiency of operation.

[0011] Furthermore, a second screw for securing the fixing rope is threaded onto the fixing block. The design of the second screw provides an additional fixing point for the fixing rope, further enhancing its stability and ensuring that the tubular object will not fall off or be damaged during transportation due to loosening of the fixing rope.

[0018] The following detailed description illustrates the specific implementation method:

[0019] The reference numerals in the accompanying drawings include: protective pad 1, buckle 11, first screw 12, through hole 13, caster wheel 2, bracket 3, arc plate 4, fixing rope 5, fixing mechanism 6, fixing block 61, clearance hole 62, fixing ball 63, limit hole 64, spring 65, guide rod 66, fixing rod 67, and second screw 68.

[0020] Example 1 is basically as shown in the appendix. Figures 1-2 As shown: A trolley for assisting the movement of a tubular object includes a bracket 3 and casters 2 installed at the bottom of the bracket 3; the bracket 3 is welded from multiple steel plates, and the overall structure of the bracket 3 is similar to a triangle. There are three casters 2, all of which are installed at the bottom of the bracket 3 and are respectively close to the three corners of the bracket 3; an arc-shaped plate 4 adapted to the tubular object is bolted to the top of the bracket 3. The arc-shaped plate 4 is bent upward, and a protective pad 1 is provided on the side of the arc-shaped plate 4 away from the bracket 3. Specifically, the protective pad 1 has buckles 11 on both sides for engaging with the arc-shaped plate 4, and the contact parts of the buckles 11 and the arc-shaped plate 4 are fixed by adhesive.

[0021] Example 2 is basically as shown in the appendix. Figure 3 As shown, the only difference between it and Embodiment 1 is that the buckle 11 and the arc plate 4 are not fixed by adhesive, but by a detachable connection. Specifically, the outer wall of the arc plate 4 is provided with a threaded hole, the buckle 11 is provided with a connecting hole, and a first screw 12 that cooperates with the threaded hole is provided in the connecting hole. The buckle 11 and the arc plate 4 are fixedly connected by the first screw 12.

[0022] Example 3 is basically as shown in the appendix. Figure 4 As shown, the difference between this embodiment and Embodiment 2 is only that: a fixing rope 5 is fixedly connected to the bracket 3, and three through holes 13 for the fixing rope 5 to pass through are provided on both sides of the arc plate 4 and the protective pad 1, with the three through holes 13 arranged sequentially from bottom to top on the arc plate 4 and the protective pad 1; in addition, the bracket 3 is also provided with a fixing mechanism 6 for fixing the fixing rope 5, and the fixing mechanism 6 and the fixing rope 5 are located on both sides of the arc plate 4; the fixing mechanism 6 is as shown in the attached figure. Figure 5As shown: It includes a fixing block 61, and a horizontal clearance hole 62 for fixing the rope 5 to pass through is provided in the fixing block 61. The clearance hole 62 passes through the fixing block 61. The fixing block 61 has three sets of holes, including guide holes and limiting holes 64 arranged sequentially from top to bottom on the fixing block 61. The guide holes and limiting holes 64 are coaxial and interconnected. The diameter of the guide hole is smaller than the diameter of the limiting hole 64. The limiting hole 64 is connected to the clearance hole 62. A guide rod 66 is vertically slidably connected in the guide hole. One end of the guide rod 66 extends into the limiting hole 64 and is fixedly connected to a fixing ball 63. A spring 65 is sleeved on the guide rod 66. One end of the spring 65 abuts against the fixing ball 63, and the other end of the spring 65 abuts against the side wall of the top of the limiting hole 64. The three guide rods 66 are fixedly connected to the same fixing rod 67.

[0023] The only difference between Example 4 and Example 3 is the fixing mechanism 6, as shown in the attached diagram. Figure 6 As shown, a second screw 68 for fixing the fixing rope 5 is threaded onto the fixing block 61. The second screw 68 fixes the free end of the fixing rope 5 to prevent the fixing rope 5 from completely detaching from the fixing block 61.

[0024] Taking Example 4 as an example, the specific implementation process is as follows: First, based on the diameter and length of the tubular object, a suitable trolley (hereinafter referred to as the trolley for ease of discussion) is selected to assist in moving the tubular object. Next, the trolleys are placed on the ground, with each trolley spaced approximately 5 meters apart (this arrangement ensures that the tubular object receives uniform support and protection during transportation), and ensures that the casters 2 can rotate freely. This facilitates easy movement of the trolleys during transportation and reduces friction and resistance.

[0025] Then, the tubular object is placed on the curved plate 4, ensuring that it is in direct contact with the protective pad 1. The protective pad 1 can protect the tubular object from damage during transportation and provide a certain cushioning effect to reduce the impact caused by uneven roads or vibrations; the trolley can be added, removed, and adjusted according to actual needs to accommodate tubular objects of different lengths and weights.

[0026] Next, use the fixing rope 5 to firmly fix the tubular object to the arc plate 4 and the protective pad 1. Pass the free end of the fixing rope 5 through the through hole 13 and around the outer wall of the tubular object, and then pass the other end through another through hole 13. Then, lift the guide rod 66 by the fixing rod 67, so that the fixing ball 63 disengages from the clearance hole 62, and the fixing rope 5 passes through the clearance hole 62 to fix the tubular object. Release the fixing rod 67, and under the action of the spring 65, the fixing ball 63 enters the clearance hole 62 to fix the fixing rope 5. Then, fix the free end of the fixing rope 5 with the second screw 68 to prevent it from completely detaching from the fixing block 61 during transportation.

[0027] During transportation, the omnidirectional wheels 2 of the trolley can easily handle different terrains, reducing friction and resistance and protecting the tubular object from damage. Meanwhile, the protective pad 1 and the fixing mechanism 6 provide additional protection and fixation, ensuring the stability and safety of the tubular object during transportation. When the road surface is uneven and causes the tubular object to tilt, the upward movement of the tubular object causes part of the fixing rope 5 to rise. The fixing rope 5 acts on the corresponding fixing ball 63. Due to the elasticity of the spring 65, the fixing ball 63 can move upwards appropriately as the fixing rope 5 rises, allowing the fixing rope 5 to be partially lowered.

[0028] The above descriptions are merely embodiments of this utility model, and common knowledge regarding specific structures and characteristics is not elaborated upon here. It should be noted that those skilled in the art can make various modifications and improvements without departing from the structure of this utility model, and these should also be considered within the scope of protection of this utility model. These modifications will not affect the effectiveness of the implementation of this utility model or the practicality of the patent. The scope of protection claimed in this application shall be determined by the content of its claims, and the specific embodiments described in the specification can be used to interpret the content of the claims.
