Description

Technical Field

[0001] The invention relates to the technical field of vehicle-blocking devices, in particular to a remote pneumatic vehicle-blocking device for coal mines. Background Art

[0002] The car blocker used in coal mines is a braking device used to apply resistance to the tires of vehicles. At present, the manual car blockers used in coal mines are in a normally closed state under normal circumstances. When the mine car needs to be lifted or lowered, the car blocker is opened manually, and when the mine car passes, it is closed manually. However, in this process, the mine car is prone to offside, and because the operating lever is located next to the track, the safety of the operators is difficult to be effectively guaranteed; and because the operation is too cumbersome and complicated, the operators sometimes leave the car blocker in a traffic state for a long time, which poses a serious threat to the safety of slope transportation.

[0003] Therefore, we specially designed a remote pneumatic car-blocking device for coal mines, which consists of a pneumatic push rod, a remote control room, a manual car-blocking device, and a transmission mechanism. The staff only needs to remotely control the pneumatic push rod in the remote control room to drive the transmission mechanism to open and close the car-blocking device, thereby achieving the purpose of remotely controlling the car-blocking device, ensuring the safety of the operating personnel, and improving the safety of transportation. Summary of the invention

[0004] In view of the above-mentioned deficiencies in the prior art, the present invention aims to provide a remote pneumatic vehicle arresting device for coal mines.

[0005] In order to solve the above technical problems, the present invention adopts the following technical solutions:

[0006] The present invention provides a remote pneumatic car-blocking device for coal mines, comprising a car-blocking device body, and also comprising a cylinder, a first push rod, a second push rod, a connecting plate and an air pipe. A cylinder is welded on the right side of the car-blocking device body, and the right end of the cylinder is connected to an external air control chamber through an air pipe; one end of the first push rod is welded to the left end of a piston rod in the cylinder, and the other end of the first push rod is welded to a car-blocking claw in the car-blocking device body; the first push rod is hinged to the second push rod through a connecting plate near the other end, and the other end of the second push rod is welded to another car-blocking claw in the car-blocking device body to form a rocker transmission mechanism for facilitating remote control of opening / closing the car-blocking claw, which is simple to operate, saves time and effort, and ensures the safety of operators; the center position of the connecting plate is rotatably connected to the car-blocking device body through a screw positioning pin shaft, so as to facilitate the operation of the rocker transmission mechanism.

[0007] Preferably, an air control box is provided in the external air control chamber, and the cylinder is connected to the air control box through an air pipe, so that the pressure in the cylinder can be controlled by the air control box, driving the rocker transmission mechanism to run to the right or left, making it convenient for the staff to operate and control the opening / closing of the car blocker, and the operation is convenient and labor-saving.

[0008] Preferably, the external air control chamber is arranged away from the car arrester body, so as to achieve the purpose of remote control.

[0009] The beneficial effects of the present invention are as follows: the remote pneumatic car-blocking device for coal mines in the present invention is composed of a pneumatic push rod, a remote control room, a manual car-blocking device, and a transmission mechanism. The staff only needs to remotely control the pneumatic push rod in the remote control room to drive the transmission mechanism to operate, so that the car-blocking device can be opened and closed, and the operation is convenient and quick. This solves the problem that the safety of the operating personnel of the manual car-blocking device currently used in coal mines is difficult to be effectively guaranteed because the operating rod is located next to the track. This effectively guarantees the safety of the operating personnel and improves the safety of transportation. BRIEF DESCRIPTION OF THE DRAWINGS

[0016] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0017] Embodiment 1, as Figures 1 to 3 As shown, a remote pneumatic car-blocking device for coal mines includes a car-blocking device body 6, and also includes a cylinder 1, a first push rod 2, a second push rod 3, a connecting plate 4 and an air pipe 5. The cylinder 1 is welded on the right side of the car-blocking device body 6, and the right end of the cylinder 1 is connected to the external air control chamber 8 through the air pipe 5; one end of the first push rod 2 is welded to the left end of the piston rod in the cylinder 1, and the other end of the first push rod 2 is welded to a car-blocking claw 7 in the car-blocking device body, the first push rod 2 is hinged to the second push rod 3 through the connecting plate 4 near the other end, and the other end of the second push rod 3 is welded to another car-blocking claw 7 in the car-blocking device body 6, and is combined into a rocker transmission mechanism for facilitating remote control of opening / closing the car-blocking claw, which is simple to operate, saves time and effort, ensures the safety of the operator, and is convenient for blocking mine cars; the center position of the connecting plate 4 is rotatably connected to the car-blocking device body 6 through a screw positioning pin shaft, which is used to facilitate the operation of the rocker transmission mechanism.

[0018] Among them, it should be noted that when installing the car arrester, it is necessary to adaptively adjust the length of the air pipe to lengthen or shorten it according to the location of the installation of the air control chamber.

[0019] Further, such as Figure 1 As shown, an air control box 9 is provided in the external air control chamber 8, and the cylinder 1 is connected to the air control box 9 through the air pipe 5, so that the pressure in the cylinder can be controlled by the air control box to drive the rocker transmission mechanism to run to the right or left, which is convenient for the staff to operate and control the opening / closing of the car blocker, and the operation is convenient and labor-saving.

[0020] Further, such as Figure 1 As shown, the external air control chamber 8 is arranged far away from the car arrester body 1, so as to achieve the purpose of remote control.

[0021] When the remote pneumatic vehicle blocking device for coal mines in this embodiment is actually used, the staff only needs to operate the pneumatic control box located at a distance to remotely control the pneumatic push rod to drive the transmission mechanism to operate, so that the vehicle blocking device is opened and closed, and the operation is convenient and fast, thereby ensuring the safety of the operating personnel and improving the safety of transportation. The specific method is as follows:

[0022] (1) The staff opens the air control valve on the air control box and transmits compressed air through the air pipe to increase the pressure in the cylinder, so that the piston rod in the cylinder extends, and then pushes the first push rod to the left to drive the left car blocking claw to open. At this time, the first push rod drives one end of the connecting plate to rotate counterclockwise, so that the other end of the connecting plate rotates in phase, thereby pushing the second push rod to the right, and then driving the right car blocking claw of the car blocker to open, so as to block the mine car that is out of control or landslides, and avoid accidents.

[0023] (2) When a vehicle passes, the staff operates the air control valve on the air control box to close it, and the air pipe stops supplying compressed air to the cylinder, so that the pressure in the cylinder is reduced and the cylinder piston rod is reset, thereby pulling the first push rod to the right to drive the left side of the car blocker to close. At this time, the first push rod drives one end of the connecting plate to rotate clockwise, so that the other end of the connecting plate rotates in phase, thereby pulling the second push rod to the left, and then driving the right side of the car blocker The claw is closed, ensuring the smooth passage of the mine car.

[0024] Obviously, the above-mentioned embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit them; although the present invention has been described in detail with reference to the above-mentioned embodiments, those skilled in the art should understand that they can still modify the technical solutions recorded in the above-mentioned embodiments, or replace part or all of the technical features therein by equivalents; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the scope of the technical solutions of the embodiments of the present invention. Thus, if these modifications and variations of the present invention fall within the scope of the claims of the present invention and their equivalent technologies, the present invention is also intended to include these modifications and variations.
