Description

Technical Field

[0001] This utility model relates to the technical field of cable protection devices, and in particular to a protective device for connecting electromechanical wires in mining applications. Background Technology

[0002] Mining electromechanical equipment refers to mechanical and electrical equipment used in mining, transportation, ventilation, and other processes. The use of mining electromechanical equipment located in roadways requires the pre-laying of different types of cables in the roadways in order to enable the normal operation of the mining electromechanical equipment.

[0003] Because the overhead space of the tunnel is often occupied by ventilation ducts, drainage pipes, etc., and the top rock conditions are complex, there is a risk of loose rocks falling. Some cables are laid along the ground inside the tunnel. When laying cables on the ground inside the tunnel, there is a lack of specialized and flexible protective devices. It is impossible to easily adjust the protective space according to the cable diameter. As a result, some thinner or thicker cables are difficult to protect properly and are easily damaged by mechanical force, affecting the normal use of the cables and thus interfering with the operation of mining electromechanical equipment. Utility Model Content

[0004] The purpose of this utility model is to provide a protective device for connecting electromechanical wires in mining, which has the characteristics of adjustable protective space and stable connection of multiple protective structures, and can effectively solve the problems in the background art.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0006] A protective device for connecting electrical wires in mining applications includes two side plates. A horizontal plate is fixedly installed on one side of each side plate, and a connecting plate is movably connected between the two horizontal plates. Two bearing seats are fixedly installed on one side of each side plate, and a slot is formed on one side of each side plate away from the bearing seats. A shaft hole is formed in each of the two bearing seats, and a pin is inserted into the two shaft holes. A push block is also movably installed between the two bearing seats, and the push block is close to the shaft hole.

[0007] As a further preferred embodiment of this utility model, two sliding grooves are provided on opposite sides of the two shaft seats, and one side of the two sliding grooves is aligned with the center point of the shaft hole. The two shaft seats, in conjunction with the sliding grooves provided inside, can provide a foundation for the installation of the push block and realize the radial movement of the push block.

[0008] As a further preferred embodiment of this utility model, multiple limiting blocks are fixedly installed on the top and bottom sides of the horizontal plate away from the side plate.

[0009] As a further preferred embodiment of this utility model, the connecting plate has a slot, and the bottom of the slot has multiple limiting grooves. The horizontal plate is inserted into the slot on one side, and the upper end of the limiting block is inserted into the corresponding limiting groove. The two side plates are connected to the connecting plate through the horizontal plate. The enclosed space of the two sets of side plates, horizontal plates and connecting plates can be adjusted according to the cable laying requirements of different diameters.

[0010] As a further preferred embodiment of this utility model, sliders are fixedly installed on both sides of the push block, and a guide slope is provided on the push block located between the two sliders. The sliders are slidably connected in the corresponding grooves. The push block is installed between the two bearing seats through the sliders and the guide slope is provided, so that the push block can be squeezed and moved when the pin is fixed to the side plate. An L-shaped locking block is fixedly installed on one side of one of the sliders. The L-shaped locking block can be locked into the locking groove on the side of the adjacent side plate, so that when the side plate is fixed, the two adjacent side plates are connected simultaneously.

[0011] As a further preferred embodiment of this utility model, a metal spring is fixedly installed on one side of the push block relative to the side plate, and the two ends of the metal spring abut against one side of the side plate respectively. With the deformation capability of the metal spring, the push block can be reset and pushed when the pin is pulled out from the shaft hole.

[0012] As a further preferred embodiment of this utility model, a plurality of anti-detachment protrusions are fixedly installed on the outer side of the pin, and an end seat is fixedly installed on the upper end of the pin. The longitudinal section of the end seat is I-shaped. By setting the end seat on the pin, it is convenient to remove the lower end of the pin from the formation with the help of tools.

[0013] Compared with the prior art, the present invention has the following beneficial effects:

[0014] In this utility model, the two sets of side plates and the cross plate are movably connected by a connecting plate, which can quickly adjust the protective space according to the cable laying requirements of different diameters. At the same time, the cooperation of the pin, the shaft seat, the push block, and the L-shaped locking block can simultaneously connect two adjacent side plates when the side plates are fixed on the ground, thereby achieving the stability of the connection and assembly of multiple protective structures.

[0021] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0022] like Figures 1-5 As shown, the present invention provides a protective device for connecting electrical wires in mining machinery, including two side plates 1. A horizontal plate 2 is fixedly installed on one side of each side plate 1, and a connecting plate 3 is movably connected between the two horizontal plates 2. Two bearing seats 4 are fixedly installed on one side of each side plate 1. A slot 18 is provided on one side of each side plate 1 away from the bearing seats 4. A shaft hole 5 is provided in each of the two bearing seats 4. A pin 6 is inserted into the two shaft holes 5. A push block 7 is also movably installed between the two bearing seats 4, and the push block 7 is close to the shaft hole 5.

[0023] like Figures 2-5As shown, each of the two bearing seats 4 has two sliding grooves 11 on one side, and one side of each sliding groove 11 is aligned with the center point of the shaft hole 5. The two bearing seats 4, in conjunction with the internal sliding grooves 11, provide a foundation for the installation of the push block 7 and enable the radial movement of the push block 7. Slider blocks 12 are fixedly installed on both sides of the push block 7. The push block 7 located between the two sliders 12 also has a guide slope 13, and the sliders 12 are slidably connected in the corresponding sliding grooves 11. The push block 7 is installed between the two bearing seats 4 through the sliders 12 and the guide slope 13 is provided, so that the push block 7 can be pressed and moved when the pin 6 is fixed to the side plate 1. One of the sliders 12 has an L-shaped clip fixedly installed on one side. Block 14, L-shaped locking block 14 can be locked into the slot 18 on one side of the adjacent side plate 1, so that when the side plate 1 is fixed, the two adjacent side plates 1 are connected at the same time. The push block 7 is fixedly installed with a metal spring 15 on one side of the side plate 1, and the two ends of the metal spring 15 abut against one side of the side plate 1 respectively. With the deformation ability of the metal spring 15, the push block 7 can be reset and pushed when the pin 6 is pulled out from the shaft hole 5. Multiple anti-disengagement protrusions 16 are fixedly installed on the outside of the pin 6. An end seat 17 is fixedly installed on the upper end of the pin 6. The longitudinal section of the end seat 17 is I-shaped. The end seat 17 on the pin 6 makes it easy to remove the lower end of the pin 6 from the formation with the help of tools.

[0024] like Figures 2-3 As shown, multiple limiting blocks 8 are fixedly installed on the top and bottom sides of the horizontal plate 2 away from the side plate 1. The connecting plate 3 has a slot 9, and multiple limiting grooves 10 are opened at the bottom and bottom of the slot 9. The horizontal plate 2 is inserted into the slot 9 on one side, and the upper end of the limiting block 8 is inserted into the corresponding limiting groove 10. The two side plates 1 are connected to the connecting plate 3 through the horizontal plate 2. The enclosed space of the two sets of side plates 1, horizontal plate 2 and connecting plate 3 can be adjusted according to the cable laying requirements of different diameters.

[0025] It should be noted that this utility model is a protective device for connecting electrical wires in mining machinery. When adjusting the enclosed space of the side plate 1, the horizontal plate 2 and the connecting plate 3, the two side plates 1 can be manually pulled to one side respectively. Then, the horizontal plates 2 on one side of the two side plates 1 move in the slots 9 of the connecting plate 3 respectively. By changing the insertion depth of the horizontal plate 2 in the slots 9, the size of the space enclosed by the two sets of side plates 1, horizontal plates 2 and connecting plates 3 can be adjusted, thereby providing a suitable protective space for cables of different thicknesses.

[0026] In addition, when fixing the side plate 1, the combined structure of the side plate 1, the cross plate 2, and the connecting plate 3 can be first covered on the cable, so that the lower end of the side plate 1 and one of the L-shaped locking blocks 14 touch the ground. Then, when the pin 6 is inserted into the shaft hole 5, the pin 6 presses the guide slope 13 on the push block 7, and the sliders 12 on both sides of the push block 7 slide in the groove 11 of the shaft seat 4, pushing the push block 7 to move, so that the L-shaped locking block 14 fixed on one side of the slider 12 is locked into the slot 18 of the adjacent side plate 1. In this way, while fixing the side plate 1 to the ground, the connection of the adjacent side plates 1 is realized simultaneously, ensuring the stable connection and assembly of multiple protective structures. Finally, the lower end of the pin 6 is inserted into the stratum in the tunnel, and the limiting and fixing of the side plate 1 is completed.

[0027] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model.
