Description

Technical Field

[0001] This utility model belongs to the technical field of single-column trolleys, specifically relating to a rapid lifting single-column trolley for coal mines. Background Technology

[0002] In underground coal mining operations, single-pillar supports are commonly used support equipment. Due to the complex working environment and confined space underground, as well as the large size and heavy weight of single-pillar supports, their transportation has always been a challenging task.

[0003] Traditional methods of transporting single columns rely heavily on manual labor, which is not only labor-intensive and inefficient but also poses significant safety risks, easily leading to worker injuries. Although some simple handling tools exist, they generally suffer from problems such as unreasonable structural design, slow handling speed, and poor adaptability.

[0004] For example, some transport trolleys cannot securely hold individual columns, making them prone to slipping during transport; others have wheel designs unsuitable for the complex underground terrain, leading to jamming and tipping, severely impacting the efficiency and safety of column transport. Therefore, developing an efficient, safe, and adaptable rapid column transport trolley for coal mines is of significant practical importance. Summary of the Invention

[0005] In view of the shortcomings of the existing technology, this utility model provides a rapid lifting trolley for single columns in coal mines to solve the problems of slow handling speed and poor adaptability mentioned in the background technology, which affect the handling efficiency and safety of single columns.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a rapid lifting trolley for single columns in coal mines, comprising: The trolley shell has a handle for quickly lifting single-column tools installed on its surface; A single-unit column gripper switch is installed on the surface of the trolley shell. The single-unit column gripper switch is movably connected to the trolley shell. A steel wire rope is installed on the surface of the single-unit column gripper switch. A first single-unit column gripper is installed on one side of the bottom of the trolley shell, and a second single-unit column gripper is installed on the other side of the bottom of the trolley shell. The steel wire rope is connected to the first single-unit column gripper and the second single-unit column gripper respectively. Wheels are located at the bottom of the trolley shell. Brake pads are installed at the bottom of the trolley shell corresponding to the positions of the wheels. A quick-lifting single-unit column tool brake handle is movably installed on the surface of the trolley shell. A brake connecting rod is installed on the surface of the quick-lifting single-unit column tool brake handle, and the brake connecting rod is connected to the brake pads.

[0007] Furthermore, connecting blocks are installed on both sides of the surface of the trolley shell, and connecting plates are installed on the surfaces of the first and second single-unit column grippers. The connecting blocks are connected to the surfaces of the connecting plates, and the connecting blocks and connecting plates are securely connected by bolts. This connection method is not only convenient for installation and disassembly, but also ensures the stability of the structure after connection, effectively preventing loosening during use and ensuring that the first and second single-unit column grippers can reliably grip the single column.

[0008] Furthermore, the surface of the handrail of the quick-lifting single column tool is fitted with an anti-slip rubber sleeve, and the surface of the anti-slip rubber sleeve is evenly distributed with grooves. The evenly distributed grooves can increase the friction between the hand and the handrail, so that the operator can firmly grip the handrail.

[0009] Furthermore, a flexible buffer pad is installed on the surface of the single-unit column gripper switch. The flexible buffer pad has a cylindrical design and is adhered to the surface of the single-unit column gripper switch. The flexible buffer pad is made of a material with good elasticity, which can protect the operator's hands during use and prevent injury to the hands due to collision.

[0010] Furthermore, the surface of the wheel is uniformly covered with wear-resistant protrusions, which are evenly distributed along the circumference of the wheel. The wear-resistant protrusions are semi-circular in design and made of high-strength wear-resistant material, which can effectively enhance the friction between the wheel and the ground, improve the grip of the vehicle during driving, and prevent slippage.

[0011] Furthermore, rubber pads are installed on the inner walls of the first and second single-unit column grippers. The surface of the rubber pads is provided with anti-slip textures to prevent direct contact between the single-unit column and the gripper, thus avoiding damage. At the same time, the anti-slip textures on the surface of the rubber pads can increase the friction between the single-unit column and the gripper, making the grip more secure and preventing the single-unit column from slipping during the lifting process, thereby improving the safety and reliability of the lifting operation. Beneficial effects

[0012] This coal mine uses a rapid-lift trolley for transporting individual columns. Through a handrail and wheels mounted on the bottom of the trolley, operators can propel the trolley using the handrail to quickly transport individual columns to designated locations, reducing the time spent transporting columns from start to finish and thus improving underground production efficiency. Simultaneously, it reduces the likelihood of the trolley getting stuck in muddy or rugged underground tunnels, lowering the risk of tipping over due to uneven surfaces and enhancing safety during transport. Furthermore, operators can adjust the clamping position of the first and second individual column grippers via a steel cable by manipulating the individual column gripper switch, securely holding individual columns of different diameters and preventing slippage during transport, further ensuring operator safety and reducing the risk of equipment damage due to slippage.

[0015] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0016] This utility model provides a technical solution: a rapid lifting single column trolley for coal mines, as shown in the figure, including a trolley shell 1, and a rapid lifting single column tool handle 2 installed on the surface of the trolley shell 1; A single column gripper switch 3 is set on the surface of the trolley shell 1. The single column gripper switch 3 is movably connected to the trolley shell 1. A steel wire rope 5 is installed on the surface of the single column gripper switch 3. A first single column gripper 7 is installed on one side of the bottom of the trolley shell 1, and a second single column gripper 10 is installed on the other side of the bottom of the trolley shell 1. The steel wire rope 5 is connected to the first single column gripper 7 and the second single column gripper 10 respectively. Wheel 8 is located at the bottom of the trolley shell 1. Brake pad 9 is installed at the bottom of the trolley shell 1 corresponding to the position of wheel 8. A quick-lifting single column tool brake handle 4 is movably installed on the surface of the trolley shell 1. A brake connecting rod 6 is installed on the surface of the quick-lifting single column tool brake handle 4. The brake connecting rod 6 is connected to the brake pad 9.

[0017] The quick-lifting single-column tool handle 2, in conjunction with the wheels 8 mounted on the bottom of the trolley shell 1, allows operators to push the trolley forward, eliminating the need for manual carrying or lifting of single columns. This enables rapid transport of single columns to designated locations, reducing the time spent transporting them from the starting point to the destination and thus improving production efficiency in underground coal mines. Furthermore, the specially designed wheels 8, forming a stable mounting structure with the bottom of the trolley shell 1, prevent the trolley from getting stuck in muddy, rugged roadways or other complex terrain conditions, reducing the risk of tipping over due to uneven surfaces and enhancing transport efficiency. The process ensures safety. Furthermore, by movably installing a single-column gripper switch 3 on the surface of the trolley housing 1, and connecting the steel wire rope 5 mounted on the surface of the single-column gripper switch 3 to the first single-column gripper 7 and the second single-column gripper 10 on both sides of the bottom of the trolley housing 1, the operator can adjust the clamping state by manipulating the single-column gripper switch 3 and using the steel wire rope 5 to drive the first single-column gripper 7 and the second single-column gripper 10. This clamping structure can adapt to single columns of different diameters and achieve a firm clamping, preventing the single column from slipping during transportation, further ensuring the safety of the operator, and also reducing the risk of equipment damage caused by the slipping of the single column.

[0018] Connecting blocks 11 are installed on both sides of the surface of the trolley shell 1. Connecting plates 12 are installed on the surfaces of the first single column gripper 7 and the second single column gripper 10. The surfaces of the connecting blocks 11 and the connecting plates 12 are connected. The connecting blocks 11 and the connecting plates 12 are securely connected by bolts. This connection method is not only convenient to install and disassemble, but also ensures the stability of the structure after connection, effectively preventing loosening during use and ensuring that the first single column gripper 7 and the second single column gripper 10 can reliably grip the single column.

[0019] The surface of the handrail 2 for quickly lifting single column tools is fitted with an anti-slip rubber sleeve 13. The surface of the anti-slip rubber sleeve 13 is evenly distributed with grooves. The evenly distributed grooves can increase the friction between the hand and the handrail, so that the operator can firmly grip the handrail.

[0020] A flexible buffer pad 14 is installed on the surface of the single column gripper switch 3. The flexible buffer pad 14 is cylindrical in design and is bonded to the surface of the single column gripper switch 3. The flexible buffer pad 14 is made of a material with good elasticity, which can protect the operator's hands during use and prevent injury to the hands due to collision.

[0021] The surface of the wheel 8 is evenly covered with wear-resistant protrusions 15. The wear-resistant protrusions 15 are evenly distributed along the circumference of the wheel 8. The wear-resistant protrusions 15 are semi-circular in design and are made of high-strength wear-resistant material. They can effectively enhance the friction between the wheel 8 and the ground, improve the grip of the car during driving, and prevent slippage.

[0022] Please see Figure 2 The inner walls of the first single column gripper 7 and the second single column gripper 10 are equipped with rubber pads 101. The surface of the rubber pads 101 is provided with anti-slip texture to prevent the single column from directly contacting the gripper and causing damage. At the same time, the anti-slip texture on the surface of the rubber pads 101 can increase the friction between the single column and the single column, making the grip more secure, preventing the single column from slipping during the lifting process, and improving the safety and reliability of the lifting operation.

[0023] In use: The operator holds the handle 2 of the quick-lifting single column tool, which is fitted with an anti-slip rubber sleeve 13, and pushes the trolley to the single column with the help of the wheels 8 with wear-resistant protrusions 15 installed at the bottom of the trolley shell 1; the single column gripper switch 3 with a flexible buffer pad 14 on the control surface drives the first single column gripper 7 and the second single column gripper 10, which are firmly connected to the trolley shell 1 via the steel wire rope 5, to adjust the clamping state. The rubber pad 101 on the inner wall of the gripper prevents damage to the single column and its anti-slip texture increases friction, so as to achieve a firm gripping of single columns of different diameters; during transportation, the special design of the wheels 8 and the wear-resistant protrusions 15 make the trolley less likely to get stuck or tip over on complex road surfaces. If braking is required, the quick-lifting single column tool brake handle 4 is pulled, and the brake pads 9 are driven by the brake connecting rod 6 to achieve braking, and finally the single column is quickly transported to the designated location.

[0024] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
