[0002] In the process of mine rail transportation, the blocking, stopping and positioning of mine cars are mainly achieved through car blocking devices. The use of car blocking devices is not only large in number and high in frequency, but also the accuracy of their action is related to the reliability and safety of blocking mine cars.

[0003] At present, the blocking device in the mine track transportation mostly adopts the track holding form. In this form, a blocking claw is set on the outer side of each of the two tracks to block the mine car wheels. Through single-axis rotation and multi-link transmission, a pair of blocking claws are opened or closed. The single-axis driven blocking device has the problems of complex multi-link adjustment, inaccurate blocking claw action position, poor synchronization of the two blocking claws, etc., which reduces the reliability of the blocking device. In addition, the hydraulic cylinder is used as the driving source. When the equipment is running, a hydraulic station is established as the energy source, which not only increases the production cost of the equipment, but also increases the floor space.

[0004] Therefore, in view of the above problems, an electric-driven vehicle-blocking device is proposed. Utility Model Content

[0019] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0020] Specific examples are given below.

[0021] See also Figure 1 - Figure 2 The utility model provides an electric-driven car-blocking device, including a base 9; the rear sides of both sides of the inner cavity of the base 9 are fixedly connected with a blocking claw seat 6, the surface of the blocking claw seat 6 is slidably connected with a blocking claw 1, the opposite sides of the two blocking claws 1 are hingedly connected with a blocking claw connecting rod 2, the opposite sides of the two blocking claw connecting rods 2 are hingedly connected with a transmission connecting rod 3, one of the transmission connecting rods 3 is fixedly connected with a driving shaft 4 on the right side, and the other transmission connecting rod 3 is fixedly connected with a driven shaft 5 on the left side, and the surfaces of the driving shaft 4 and the driven shaft 5 are fixedly connected with a transmission gear 7, and the two transmission gears 7 are meshed with each other, and the rear side of the driving shaft 4 is fixedly connected with a driving rod 8; the left side of the driving rod 8 is hingedly connected with an electric cylinder 10, and when the driving rod 8 is pushed by the electric cylinder 10, the driving rod 8 drives the driving shaft 4 rotates, and the transmission gear 7 and the transmission connecting rod 3 on the driving shaft 4 rotate accordingly. Through the meshing transmission of the two transmission gears 7, the driven shaft 5 and the transmission gear 7 and the transmission connecting rod 3 connected thereto rotate synchronously. The two transmission connecting rods 3 pull the blocking pawl connecting rods 2 respectively to open the two blocking pawls 1, and at this time, the rail vehicle can pass. When the electric cylinder 10 pushes the driving rod 8 in the opposite direction, the blocking pawl 1 can move to a closed state. The coordinated use of the above structure has the following beneficial effects. The closing and opening of the blocking pawl 1 of the utility model are controlled by a left-right symmetrical structure and size. Through the meshing of the transmission gear 7, the left and right blocking pawls 1 move synchronously. Each blocking pawl 1 is connected by its own blocking pawl connecting rod 2 and transmission. The structure is relatively simple and independent, which makes the blocking pawl action position more accurate and more reliable to use.

[0022] Further, such as Figure 2As shown, the blocking claw seat 6 includes a threaded rod 11, and the front side of the threaded rod 11 is movably connected to the rear side of the inner cavity of the base 9; the surface of the threaded rod 11 is fixedly connected to the blocking claw 1, and a spring 12 is sleeved on the surface of the threaded rod 11, and the front side of the spring 12 is fixedly connected to the rear side of the base 9, and the rear side of the spring 12 is movably connected with a blocking ring 13, and the inner cavity of the blocking ring 13 is movably connected to the threaded rod 11. When the mine car needs to be blocked, the mine car hits the blocking claw 1, and the spring 12 buffers the blocking claw 1, thereby buffering the force generated when the mine car is blocked, and the threaded rod 11 is limited by the base 9, and then the position of the spring 12 is fixed by the coordinated use of the threaded rod 11 and the blocking ring 13. The coordinated use of the above structure has the following beneficial effects: it is convenient to buffer the force generated when the mine car is blocked, prevent direct impact on the equipment to cause damage to the equipment, and extend the service life of the equipment.

[0023] Further, such as Figure 1 and Figure 2 As shown, the side of the driven shaft 5 opposite to the front and rear sides of the driving shaft 4 is movably connected to the inner cavity of the base 9 through a rotating pair, and the driven shaft 5 is arranged on the side close to the driving shaft 4. By setting the driven shaft 5, the driving shaft 4 and the base 9 for coordinated use, the effect of facilitating the position limitation of the driven shaft 5 and the driving shaft 4 when the equipment is in use is achieved.

[0024] Further, such as Figure 2 As shown, a nut 14 is threadedly connected to the rear side of the threaded rod 11, and the side of the nut 14 close to the barrier ring 13 is fixedly connected to the barrier ring 13. When the tensile force of the spring 12 needs to be adjusted, the nut 14 is rotated to drive the barrier ring 13 to move and adjust the tensile force of the spring 12.

[0025] Further, such as Figure 1 As shown, an articulated frame 15 is fixedly connected to the left side of the upper end of the electric cylinder 10, and the articulated frame 15 is fixedly connected to the lower end of the left side of the base 9. The position of the electric cylinder 10 is limited by the coordinated use of the articulated frame 15 and the base 9, thereby preventing the position of the electric cylinder 10 from moving when the equipment is in use.

[0026] Further, such as Figure 1 As shown, a frame 16 is fixedly connected to the front side of the base 9 close to the blocking claw 1, and the rear side of the inner cavity of the frame 16 contacts the blocking claw 1. By setting the frame 16, the base 9 and the blocking claw 1 for use in coordination, the effect of limiting the moving range of the blocking claw 1 is achieved.

[0027] The above shows and describes the basic principle, main features and advantages of the utility model. Those skilled in the art should understand that the utility model is not limited by the above embodiments, and the above embodiments and descriptions are only for explaining the principle of the utility model. Without departing from the spirit and scope of the utility model, the utility model may have various changes and improvements, and these changes and improvements fall within the scope of the utility model to be protected.
