Description

Technical Field

[0001] The utility model relates to a car catching device for catching a mine car in an inclined shaft and blocking the mine car, belonging to the technical field of mining machinery. Background Art

[0002] In the mining production with "safety first", accidents are no small matter, especially in the mining production with inclined shaft transportation. When mine cars enter and exit the mine, although there are complete rules and regulations and in the 24-hour uninterrupted operation, workers also have difficulties and mistakes may occur in extremely special situations. Sometimes the mine car is pushed underground without hanging the winch wire rope, and the workers underground have no defense. Especially in the process of digging the inclined shaft, there is no place for people to hide. This is an accident that cannot be thought of. Before putting the mine car underground, it is necessary to use a car blocker to block the mine car at the ground level of the wellhead, check the connection between the mine cars and the winch wire rope connection, and then open the car blocker to put the mine car underground. In case of such a runaway car accident, emergency remedial measures are required. Summary of the invention

[0003] In order to solve the above problems, a car catching device for catching a mine car in an inclined shaft is designed to prevent the mine car from continuing to slide down the shaft without the steel wire rope and causing a major accident.

[0004] In order to solve the above technical problems, a car catching device for catching and blocking mine cars in an inclined shaft comprises: rails, sleepers, double hooks, a hook shaft, a car catching device bracket, a hook counterweight, a hook shaft crank arm, drawing, a control rod, a control rod drawing ear, a control rod handle, a control sub-handle, sub-handle drawing, a positioning card, an arc-shaped positioning tooth, a control rod fixing sleeve, a wellhead wheel, a blocking wood sleeper, a car catching device straight sleeper, a sleeper locking screw, a hook shaft bearing seat, fixing screws, spikes, a car catching device bracket and a track fixing screw.

[0005] The invention is characterized in that a car catching device bracket is installed on two car catching device straight sleepers with sleeper locking screws, the car catching device straight sleepers are installed under the two sleepers with sleeper locking screws, and the rails are locked on the sleepers with rail spikes.

[0006] The car catching device bracket is locked with the track fixing screws and locked with the car catching device straight pillow with screws in the middle.

[0007] The bearing seat of the hook shaft is locked with the car catching device bracket by using fixing screws.

[0008] The hook shaft can rotate freely in the hook shaft bearing seat. Under normal circumstances, due to the downward gravity of the hook counterweight iron, the double hooks stand upright and align with the mine car axle.

[0009] A hook shaft crank arm is welded at one end of the hook shaft, and a round hole is provided at the front end. A wire is passed through the middle of the hole. When the wire is pulled upward, the double hooks are driven to fall downward, and the mine car can pass through the back of the double hooks.

[0010] The operating rod fixed shaft sleeve and the support below the operating rod are installed on the sleepers that are leveled at the wellhead. A operating rod drawing ear is welded in front of the operating rod to connect the drawing between the hook shaft crank arms.

[0011] There are arc-shaped positioning teeth under the control rod, and the tooth tips extend obliquely backwards.

[0012] The top of the operating rod is the operating rod handle, and a movable operating sub-handle is installed next to it with a threading wire. There is a round hole at the lower end of the sub-handle, and the distance between the round hole and the fixed threading wire is 30-40 mm. A wire is drawn through the sub-handle in the round hole and connected to the positioning card below. The tip of the positioning card is inserted into the arc-shaped positioning tooth to fix the position of the operating rod. A tension spring is also hung in the round hole of the sub-handle to return the sub-handle to its original position.

[0013] When the hand presses down the operating sub-handle, the sub-handle wire moves upward to pull the positioning card away from the arc-shaped positioning teeth, the operating rod will lose control, and the operating rod can be moved forward or backward. When the hand releases the operating sub-handle, the positioning card will be inserted into the arc-shaped positioning teeth, and the operating rod will be fixed in the required position.

[0014] The double hooks of the car bailer are installed in the inclined well at a distance of 30-40 meters from the wellhead.

[0015] When the car bailer is working, the operating rod is placed in the front position, the hook counterweight is pointed straight down, and the double hooks are upright. If a mine car runaway accident occurs, when the mine car slides to the car bailer position, the double hooks will hook the mine car axle to prevent the mine car from sliding down.

[0016] When lowering a mine car into the mine, the earthquake personnel must check that each mine car and wire rope are connected correctly before stepping on the car stopper to lower the car, and then pull down the car fishing device operating rod to make the double fishing hooks fall down to allow the mine car to pass.

[0017] When winching upwards, since the double hooks are one-way blocking vehicles, the shaft of the mine car only rubs against the back of the hooks and makes an impact sound, and the operating rod can remain unchanged; the operating rod can also be manually pulled down to make the hook fall down.

[0018] A car catching device for catching a mine car in an inclined shaft has the following advantages.

[0019] When the car bailer is working, the operating rod is placed in the front position, the hook counterweight is pointed straight down, and the double hooks are upright. If a mine car runaway accident occurs, when the mine car slides to the car bailer position, the double hooks will hook the mine car axle to prevent the mine car from sliding down and causing serious injuries and damage to equipment.

[0020] Under normal circumstances, the car scoop does not affect the upward winching of the ore car.

[0021] Installing a car salvor 30-40 meters away from the wellhead can give ground crews a certain amount of time to react and operate.

[0022] The mine car has a sliding distance of 30-40 meters, and the mine car has not yet generated much acceleration, which creates favorable conditions for the double hooks to hook the mine car.

[0023] The control rod is designed with a positioning control system, and the double hooks can be stopped at any position. The operation is simple and practical. BRIEF DESCRIPTION OF THE DRAWINGS

[0030] The invention is characterized in that: the car catching device bracket 5 is installed on two car catching device straight sleepers 19 with sleeper locking screws 20; the car catching device straight sleepers 19 are installed under two sleepers 2 with sleeper locking screws 20; and the track 1 is locked on the sleepers 1 with spikes 23.

[0031] The car catching device support 5 is locked with the car catching device support and the track fixing screw 24, and is locked with the car catching device straight pillow 19 with screws in the middle.

[0032] The hook shaft bearing seat 21 is locked with the car catching device bracket 5 with a fixing screw 22.

[0033] The hook shaft 4 can rotate freely in the hook shaft bearing seat 21. Under normal circumstances, due to the gravity of the hook counterweight iron 6, the double hooks 3 stand upright and align with the mine car axle.

[0034] One end of the hook shaft 4 is welded with a hook shaft crank arm 7, and a round hole is provided at the front end, and a wire drawing 8 is passed through the middle of the hole. When the wire drawing 8 is pulled upward, the double hooks 3 are driven to fall downward, and the mine car can pass through the back of the double hooks 3.

[0035] The operating rod fixing sleeve 16 and the support below the operating rod 9 are installed on the sleepers 2 that are leveled at the wellhead. A operating rod drawing ear 10 is welded in front of the operating rod 9 to connect the drawing wire 8 between the hook shaft crank arms 7.

[0036] There is an arc-shaped positioning tooth 15 below the operating rod 9, and the tooth tip extends obliquely backward.

[0037] The top of the operating rod 9 is the operating rod handle 11, and a movable operating sub-handle 12 is installed next to it with a threading wire. There is a circular hole at the lower end of the operating sub-handle 12, and the circular hole is 30-40 mm away from the fixed threading wire. A wire 13 of the sub-handle is passed through the circular hole and connected to the positioning card 14 below. The tip of the positioning card 14 is inserted into the arc-shaped positioning tooth 15 to fix the position of the operating rod 9. A tension spring is also hung in the circular hole of the operating sub-handle 12 to return the operating sub-handle 12 to its original position.

[0038] When the hand presses down the operating sub-handle 12, the sub-handle wire 13 moves upward to pull the positioning card 14 away from the arc-shaped positioning tooth 15, the operating rod 9 will lose control, and the operating rod 9 can be moved forward or backward.
