Description

Technical Field

[0001] The invention relates to the technical field of mine explosion-proof elevators, and in particular to a mine explosion-proof elevator adopting a serial communication control system. Background Art

[0002] A mine is a general term for the shafts, chambers, equipment, ground buildings and structures that form an underground coal mine production system. The underground mining industry has always used a cage or a cage hoist device to enable personnel and materials to enter the mine vertically. The cage or cage runs up and down in the vertical shaft of the mine. The wire rope on its top is introduced into the winch in the winch room through the pulley in the pulley room, and then connected to the stabilizer in the winch room. Driven by the motor, the winch pulls the cage or cage up or down in the vertical shaft of the mine through the wire rope, and the stabilizer at the other end of the wire rope goes down or up in the passage of the winch room. However, the operator controls the lifting and lowering of the cage or cage in the machine room through the monitor installed in the cage or cage, and the passengers in the cage cannot control it, nor can they transmit underground information in time.

[0003] Therefore, based on safety development, a relatively safe mine explosion-proof elevator with a serial communication control system was studied. It can be used in an environment with explosive mixed gases such as methane and coal dust. It is also suitable for use in humid, water-logged, and corrosive gas environments in the shaft.

[0004] However, the bottom of existing mine explosion-proof elevators is mostly only provided with a connecting base installed on the bottom surface, and no buffering structure is provided. As a result, when the elevator car falls unexpectedly, it cannot be buffered and protected in time, which leads to the problem that the safety of passengers cannot be guaranteed and the damage to the elevator cannot be reduced. Summary of the invention

[0005] The object of the present invention is to provide a mine explosion-proof elevator using a serial communication control system to solve the problems raised in the above background technology.

[0008] The first buffer assembly includes a shock absorbing seat, a receiving plate is fixedly installed on the top surface of the shock absorbing seat, a ventilation piece is fixedly installed inside the receiving plate, and a buffer cushion is fixedly installed on the top surface of the receiving plate.

[0009] A further improvement of the technical solution of the present invention is that the elevator outer frame includes an elevator outer frame body, a lifting drive is fixedly installed on the top surface of the elevator outer frame body, and the lifting drive is set as a traction device commonly used in elevators, a connecting rope group is fixedly installed on the control end of the lifting drive, and a reduction wheel is fixedly installed on the inner side surface of the elevator outer frame body.

Since the pulley body is on the inner side of the elevator outer frame body and has a protruding part, it moves inward when it contacts the elevator car body, thereby performing suction buffering under the action of the first spring, and since it is provided with two rows and multiple groups, a preliminary buffering operation can be achieved.

By setting a first buffer component, the shock-absorbing spring and the damping rod can be combined into a shock absorber, so that suction can be buffered when the height of the elevator box body drops. At the same time, a buffer pad is arranged on the receiving plate to prevent direct impact from causing collision with the receiving plate and causing it to break, affecting the shock-absorbing effect.

[0013] A further improvement of the technical solution of the present invention is that the ventilation component includes a protective net fixedly mounted on the surface of the receiving plate, and the protective net is provided with two upper and lower groups, a ventilation fan is fixedly installed inside the receiving plate, and the ventilation fan is connected to a control power supply, and by providing the ventilation component, the ventilation fan can be remotely controlled to cooperate with the protective net to circulate air at the bottom, thereby preventing the components below the receiving plate from rusting and being damaged due to a long-term sealing state, thereby causing the loss of the shock-absorbing effect.

By setting the alarm device, the alarm operation can be realized after the elevator car falls at high speed and is buffered by the first buffer component and the second buffer component, so as to remind workers who are not taking the elevator to carry out emergency rescue, and the arc-shaped pressure plate drives the resistance rod to move downward and collide with the sensor seat to realize the sensing operation, so that the information can be transmitted to the alarm panel through the sensor wire to light up the warning, etc.

[0016] A further improvement of the technical solution of the present invention is that the first mounting plate and the elevator outer frame body are fixedly connected by bolts, and the second mounting plate and the receiving plate are also fixedly connected by bolts. The fixing by bolts makes the installation operation simple and convenient for later disassembly, maintenance or replacement.

[0017] A further improvement of the technical solution of the present invention is that the lifting drive, elevator car control console and alarm device all adopt a serial communication control system, which can realize remote control and communication.

[0018] Due to the adoption of the above technical solution, the present invention has the following technical advances compared with the prior art:

By arranging a reduction wheel, it can provide a certain buffer when the explosion-proof elevator fails and falls at high speed. When the elevator box falls, it contacts the pulley body. Because the pulley body is on the inner side of the elevator outer frame body and has a protruding part, it will move inward when it contacts the elevator box body, so that suction buffering can be performed under the action of the first spring. Because it is provided with two rows and multiple groups, preliminary buffering operation can be achieved.

[0020] 2. The present invention provides a mine explosion-proof elevator adopting a serial communication control system. By setting a first buffer component, it can realize the combination of a shock-absorbing spring and a damping rod to form a shock absorber, so that the suction force of the elevator box body can be buffered when the height of the elevator box drops.

A ventilation part is also arranged, and the ventilation fan can be remotely controlled to cooperate with the protective net to circulate air at the bottom to prevent long-term sealing state from causing rust and damage to the components under the receiving plate, thereby causing the loss of the shock absorption effect.

[0021] 3. The present invention provides a mine explosion-proof elevator adopting a serial communication control system. By setting a second buffer component, the second buffer can be realized while the first buffer component is performing buffering and shock reduction, so that the arc-shaped pressure plate moves downward and stretches outward, thereby cooperating with the second spring to absorb the downward force.

A resistance rod is arranged under the arc-shaped pressure plate, which can collide with the sensor seat while moving downward to realize the operation of the sensor alarm.

[0022] 4. The present invention provides a mine explosion-proof elevator adopting a serial communication control system. By setting an alarm device, it can realize the alarm operation after the elevator car falls at high speed and is buffered by the first buffer component and the second buffer component, so as to remind the workers who are not in the elevator to carry out emergency rescue.

[0042] Example 3

[0043] like Figure 1-8As shown, on the basis of Embodiment 1-2, the present invention provides a technical solution: preferably, the second buffer component 4 includes a second spring 41 fixedly mounted on the surface of the bottom baffle of the elevator outer frame body 11, a connecting plate 42 is fixedly mounted on one end of the second spring 41, an arc-shaped pressure plate 43 is fixedly mounted on the surface of the connecting plate 42, and a resisting rod 44 is fixedly mounted on the bottom surface of the arc-shaped pressure plate 43. By setting the second buffer component 4, the second buffering can be realized while the first buffer component 3 performs buffering and shock absorption, so that the arc-shaped pressure plate 43 moves downward and stretches outward, so as to cooperate with the second spring 41 to absorb the downward pressure, and the efficiency of shock absorption is improved through double buffering, thereby improving the safety of the overall explosion-proof elevator, and a resisting rod 44 is arranged below the arc-shaped pressure plate 43, which can collide with the sensor seat 51 while moving downward to realize the operation of sensor alarm, and the alarm device 5 includes a sensor seat 51 fixedly mounted in the middle of the bottom surface of the elevator outer frame body 11, A sensing wire 52 is fixedly installed on the sensing end of the sensor seat 51, and an alarm panel 53 is fixedly installed on one end of the sensing wire 52, and the number of alarm panels 53 can be set according to the number of imports and exports.

[0044] The following is a detailed description of the working principle of the mine explosion-proof elevator using a serial communication control system.

[0045] like Figure 1-8 As shown, when the mine explosion-proof elevator is used, the entire mine explosion-proof elevator is installed in the mine slot, the lifting drive 12 is started to cooperate with the connecting rope group 13 to control the elevator box body 21 to move up and down, and after reaching the entrance and exit, the protective door 22 is opened, and the staff enters the elevator box body 21 and controls the up and down movement;

[0046] When a mine explosion-proof elevator fails and starts to fall at high speed, the bottom of the elevator box 21 will first contact the pulley body 143 and move it inward, and at the same time the first spring 141 absorbs the pressure and contracts to achieve initial buffering; it continues to move downward to contact the buffer pad 34 and the receiving plate 32, and at the same time the shock absorber formed by the shock-absorbing spring 312 and the damping rod 313 begins to perform the first buffering and shock absorption. When the first buffer component 3 acts, the arc pressure plate 43 begins to bend downward under the force, and realizes the second buffering and shock absorption under the action of the second spring 41, and the resistance rod 44 moves along with the collision sensor seat 51, so that the sensor wire 52 senses the signal to the alarm panel 53 to light up the light and other prompts. Because the mine explosion-proof elevator adopts a serial communication control system, it can realize the functions of remote maintenance and remote voice calls.

[0047] The above generally describes the present invention in detail, but it is obvious to a person skilled in the art that some modifications or improvements can be made to the present invention. Therefore, modifications or improvements that do not depart from the spirit of the present invention are within the scope of protection of the present invention.
