Description

Technical Field

[0001] The utility model relates to the technical field of underground cart equipment, in particular to a tank cage mine car tank filling and pushing system. Background Art

[0002] Industrial and mining enterprises often use standard-gauge or narrow-gauge railways to transport materials such as coal, ore, and construction materials. When trains or mine cars travel long distances, they are generally pulled by locomotives, such as pushers. Currently, the most commonly used pusher systems are straight-track, short-distance pushers, which cannot push carts in and out of tanks in special spaces and environments, such as non-straight tracks. The hoisting systems in many mines' secondary blind shafts use hydraulic cylinder pushers, which are fixed to the side of the cage and can only push carts out of the cage. They cannot simultaneously load and unload empty cars, requiring secondary loading and unloading, resulting in low labor efficiency. With the continuous expansion of production capacity, the problem of insufficient lifting capacity in blind shafts has become a key constraint on production. Furthermore, when loading and unloading mine cars in the middle section of the mine shaft, the inertia of the mine cars and manual assistance are used to push the carts, resulting in low labor efficiency.

[0003] To this end, the utility model provides a tank cage mine car filling and pushing system, which replaces the manual pusher, realizes efficient mechanized pusher into the tank, improves the efficiency of tank entry and exit; and is also suitable for curved transportation. Utility Model Content

[0004] The purpose of the utility model is to solve the problems existing in the prior art and to propose a cage mine car tank filling and pushing system.

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

[0006] A tank cage mine car filling and pushing system includes a liftable tank cage, an inner cage track is provided in the tank cage, and a push-in track and a push-out track are provided on the outside of the tank cage on the pushing-in and pushing-out sides of the mine car. The pushing-in track and the push-out track are both provided with a cradle on the side facing the tank cage, a circular chain pusher is provided on the pushing track, and the chain links of the circular chain pusher are universally connected. A front car stopper is provided on the pushing track close to the cradle.

[0007] Preferably, the round link chain pusher includes a driving device, a head wheel group, a tail wheel group, a round link chain, a head pusher section, a shunting pusher section, and a tail tensioning device;

[0008] The head wheel group and the tail wheel group are respectively arranged below the head and tail ends of the push-in track through supports;

[0009] The circular chain is wound between the head wheel group and the tail wheel group, and includes a plurality of chain links, each of which is divided into two rows.

A slideway that cooperates with the guide wheels on both sides is provided under the push-in track, and the slideway is arranged parallel to the push-in track. Connecting plates are rotatably installed on the rotating shafts at the ends of two adjacent chain links in the same group, and collars are welded to the opposite ends of the two adjacent connecting plates, and a fixing pin is commonly plugged between the two collars.

[0010] The head shunting section and the shunting trolley section are rotatably mounted on the connecting shaft and a tension spring is provided between the head trolley section and the connecting shaft, so that the head trolley section and the shunting trolley section always have a tendency to cling to the slideway;

[0011] The driving device comprises a hydraulic motor fixed on a support, an output shaft of the hydraulic motor is connected to a rotating shaft via a coupling, and a driving wheel matched with the connecting shaft is provided on the rotating shaft.

[0012] Preferably, a rear car stopper is provided on the pushing track at a side of the front car stopper away from the cage, and a lifting claw is provided on the pushing track at a side of the rear car stopper away from the front car stopper.

[0014] Preferably, both ends of the cage inner track are provided with upward-curved vehicle-blocking rails, and the vehicle-blocking rails are flush with the push-in track and the push-out track.

[0015] Preferably, the distance between the front car stopper and the rear car stopper is not less than the distance between the front and rear wheels of the empty mine car placed on the push-in track, and is less than the distance between the end wheels of two adjacent empty mine cars.

[0016] Preferably, the push-in track and the push-out track are both provided with a safety door on the side facing the cage, and the bottom end of the safety door is spaced apart from the cradle.

[0018] 1. After the cage reaches the wellhead, the cradle falls into place, the front car blocker is lowered and closed, and the chain pusher pushes the first empty mine car into the cage. The empty mine car then pushes the loaded mine car out of the cage onto the push-out track, completing the exchange of mine cars. The entire process is carried out automatically by machinery, without human intervention, thus reducing labor costs and safety hazards and improving operational safety. At the same time, compared with manual pushing, mechanical pushing has a stable rate and can be carried out all day, which is more efficient.

[0019] 2. The universal connection between the chain links of the circular chain pusher can be bent not only vertically but also horizontally, so that it can adapt to more complex on-site environments, including but not limited to pushing carts on curves. There is no need for secondary filling of cans, which not only improves the can discharge efficiency, but also improves the applicability and practicality of the equipment.

[0020] 3. After the cart is pushed, the cradle is raised, and the signal is sent. The hoist moves to lower the cage to the middle of the deep section. This is done in sequence to avoid continuous loading of cars, improve equipment operation safety, and complete the continuous exchange of empty mine cars with caged mine cars.

DETAILED DESCRIPTION

[0045] The following is a combination of the appended examples of the present invention Figure 1-22 , the technical solutions in the embodiments of the present invention are described clearly and completely. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0046] In Example 1, due to the constraints of on-site conditions, the car entry side of the wellhead is a curved tank entry, and traditional pushers mostly use straight roads to push carts into the tank, which are generally manually pushed into the tank, and the efficiency of manual pushers is low. In order to solve the problems existing in the prior art, reduce the labor costs and safety hazards brought by manual pushers, and at the same time enable the pusher to reduce the constraints of on-site conditions, it can be applied to pushers on curved roads. Therefore, in this embodiment, a tank cage mine car filling and pushing system is provided, including a liftable tank cage 1, wherein the tank cage 1 is provided with a cage track, and the outside of the tank cage 1 is provided with a push-in track 3 and a push-out track 4 on the pushing and pushing sides of the mine car, and the push-in track 3 and the push-out track 4 are both provided with a cradle 5 on the side facing the tank cage 1, and a circular chain pusher 9 is provided on the push-in track 3, and the chain links 903 of the circular chain pusher 9 are universally connected, and a front car blocker 6 is provided on the push-in track 3 close to the cradle 5.

[0047] Principle details of this embodiment:

[0048] A cage mine car filling and pushing system includes a cage 1 that can be raised and lowered, and the cage 1 is driven by a hoist to rise and fall in a vertical shaft. The cage 1 is provided with an internal cage track, and a cage mine car 2 is placed on the internal cage track. The outside of the cage 1 is provided with a push-in track 3 and a push-out track 4 on the mine car push-in and push-out sides respectively. The push-in track 3 and the push-out track 4 are both provided with a cradle 5 at the end facing the cage 1. The cradle 5 also has a connecting track on its bearing surface, and the connecting track is aligned with the push-in track 3, the push-out track 4, and the cage internal track. A circular chain pusher 9 is provided on the push-in track 3, and the end point of the travel of the circular chain pusher 9 is close to the corresponding side cradle 5. The chain links 903 of the circular chain pusher 9 are universally connected. A front car blocker 6 is provided on the push-in track 3 close to the cradle 5.

[0049] According to the above technical solution:

[0050] Several mine carts are arranged in sequence on the push-in track 3, connected head to tail by latches. The chain pusher 9 is activated, pushing the carts toward the cradle 5. Simultaneously, the front car blocker 6 opens and rests against the front of the carts. Once the leading cart is in position, the latch between it and the trailing cart is removed, securing the leading cart with the front car blocker 6.

[0051] When the cage 1 reaches the wellhead, the central control console receives the command, the hydraulic station 12 starts, the jacking platform 5 is lowered into place, the front car blocker 6 is lowered and closed, and the front side of the mine car is not braked. The circular chain pusher 9 starts and pushes the first empty mine car 11 into the tank, and the empty mine car 11 pushes the loaded cage car 2 onto the push-out track 4, thus completing the exchange of mine cars. After the pushing process is completed, the empty mine car 11 is located behind the front car blocker 6, and the jacking platform 5 is raised to realize the signal transmission, and the hoist is activated to lower the cage 1 to the deep middle section. This is carried out in sequence to avoid continuous loading of cars, improve the safety of equipment operation, and complete the continuous exchange of empty mine cars 11 and cage cars 2.

[0052] The entire process is performed automatically without human intervention, thus reducing labor costs and safety hazards and improving operational safety. Compared to manual pushing, mechanical pushing has a more stable rate and can be performed all day, making it more efficient. Furthermore, the universal connection between the chain links 903 of the circular chain pusher 9 allows for both vertical and horizontal bending, thus adapting to more complex on-site environments, including but not limited to pushing carts on curved roads, thereby improving the applicability and practicality of the equipment.

[0053] In this embodiment, the length of the cradle 5 is less than the wheel spacing between the front and rear sets of wheels below the empty mine car 11. In this way, after the first empty mine car 11 enters the cage 1, the second empty mine car 11 has not yet entered the range of the cradle 5, and the raising of the cradle 5 is not affected.

[0054] Example 2, in a further embodiment of this solution, a round-link chain trolley machine 9 structure suitable for different scenarios such as curves and straight roads is provided in this solution: the round-link chain trolley machine 9 includes a driving device 901, a head wheel group, a tail wheel group, a round-link chain, a head trolley section 906, a shunting trolley section 907, and a tail tensioning device;

[0055] The head wheel assembly and the tail wheel assembly are respectively arranged below the head and tail ends of the push-in track 3 through supports, and both include supports and sprockets rotatably mounted on the supports;

[0056] The circular link chain is wound between the sprockets of the head wheel group and the tail wheel group. It includes a plurality of chain links 903, and the plurality of chain links 903 are divided into two rows. The two chain links 903 of the two groups are commonly connected with a connecting shaft 908 at both ends, and guide wheels 909 are rotatably installed at both ends of the connecting shaft 908. A slide 9010 that cooperates with the guide wheels 909 on both sides is provided under the push-in track 3, and the slide 9010 is arranged parallel to the push-in track 3. Connecting plates 904 are rotatably installed on the rotating shafts at the ends of the two adjacent chain links 903 in the same group, and collars are welded to the opposite ends of the two adjacent connecting plates 904. A fixing pin 905 is commonly inserted between the two collars to realize the universal connection between the chain links 903, so that the circular link chain can bend horizontally at a bend without affecting the overall drive of the circular link chain.

[0057] The head pusher section 906 and the shunting pusher section 907 are rotatably mounted on the connecting shaft 908 and are provided with a tension spring between the head pusher section 906 and the shunting pusher section 907 so that the head pusher section 906 and the shunting pusher section 907 always tend to cling to the slideway 9010. After the head pusher section 906 abuts the rear end of the first empty mine car 11, the shunting pusher section 907 approaches the rear end of the second empty mine car 11.

[0058] The driving device 901 includes a hydraulic motor fixed on a support, and the output shaft of the hydraulic motor is connected to a rotating shaft via a coupling. The rotating shaft is provided with a driving wheel 902 that cooperates with the connecting shaft 908. The driving wheel 902 has special-shaped teeth and a plurality of slots in an array on the outer edge surface for clamping and moving the connecting shaft 908.

[0059] According to the above technical solution:

[0060] During operation, the latch between the first and second empty mine carts 11 is removed, and the hydraulic motor starts, driving the drive wheel 902 to rotate. This rotation of the drive wheel 902 shifts the connecting shaft 908 forward, thereby moving the entire chain. The chain drives the head pusher segment 906, pushing the first empty mine cart 11 into the cage 1, thereby ejecting the caged mine cart 2. Simultaneously, the shunting pusher segment 907 pushes the second empty mine cart 11 and several subsequent empty mine carts 11 to the front car blocker 6, facilitating the entry of subsequent carts. The hydraulic motor then reverses, causing the head pusher segment 906 and the shunting pusher segment 907 to move behind the second empty mine cart 11. Because the head pusher segment 906 and the shunting pusher segment 907 are rotationally connected to the connecting shaft 908, they deflect when contacting the bottom of the empty mine cart 11 during the reset process. After separating from the empty mine cart 11, they are reset by the tension spring. After the cage 1 reaches the wellhead again, the hydraulic motor drives the head pusher section 906 to push the second empty mine car 11 into the cage 1, and the process is repeated alternately to achieve continuous exchange of the empty mine car 11 with the mine car 2 in the cage.

[0061] Example 3, in a further embodiment of the present invention, a rear car stopper 7 is provided on the pushing rail 3 at the side of the front car stopper 6 facing away from the cage 1, and a lifting claw 8 is provided on the pushing rail 3 at the side of the rear car stopper 7 facing away from the front car stopper 6.

[0062] When the head pusher segment 906 reaches the rear end of the first empty mine car 11, the lifting claw 8 rises and lifts the end of the shunting pusher segment 907, causing it to deflect and become horizontal, rendering it ineffective and giving up driving the second empty mine car 11. Simultaneously, the rear car blocker 7 brakes the second empty mine car 11. This prevents the head pusher segment 906 from pushing the car into the tank, causing the shunting pusher segment 907 to drive the rear empty mine car 11 forward and over the front car blocker 6, which would pose a safety hazard. When the shunting pusher segment 907 is needed, the lifting claw 8 descends and closes, becoming inoperative.

[0063] Example 4, in a further embodiment of the present scheme, the lifting claw 8 includes a bracket fixed under the push-in track 3, a drive shaft 804 is rotatably mounted on the bracket, a crank 803 is provided at the end of the drive shaft 804, a hydraulic rod 801 is connected to the end of the crank 803, a cam 805 is mounted on the drive shaft 804, and the cam 805 abuts against a circular arc plate 806 rotatably mounted on the bracket.

[0064] Principle details of this embodiment:

[0065] The lifting claw 8 comprises a bracket fixed beneath the push-in track 3. A hydraulic rod 801 is rotatably mounted on one side of the bracket. A U-shaped bracket 802 is fixed to the protruding end of the hydraulic rod 801. A crank handle 803 abuts the opening of the U-shaped bracket 802. The end of the crank handle 803 is fixedly connected to a drive shaft 804, which is rotatably mounted on the bracket and perpendicular to the round-link chain. Cams 805 are fixed to the drive shaft 804 at intervals. The spacing between the two cams 805 is the same as the spacing between the shunting links 907 on the two links of the round-link chain. A metal arc plate 806 is rotatably mounted on the bracket.

[0066] According to the above technical solution:

[0067] When in use, the hydraulic rod 801 extends and rotates the drive shaft 804 through the crank handle 803, and the drive shaft 804 then drives the cam 805 to rotate. The cam 805 presses against the moving arc plate 806, causing the arc plate 806 to tilt upward. When the shunting trolley section 907 passes, the bottom end of the shunting trolley section 907 contacts the arc plate 806 and deflects, separating from the empty mine car 11 and becoming ineffective.

[0068] In a further embodiment of the present invention, both ends of the cage track are provided with upward-curving blocking rails, which are flush with the push-in track 3 and the push-out track 4. The blocking rails are combined with the connecting rails to form a sunken structure, thereby restraining the mine car 2 in the cage and preventing the mine car 2 from easily escaping from the cage 1.

[0069] Preferably, car stoppers are provided at both ends of the mine car 2 in the cage 1 to improve the stability of limiting the position of the mine car 2 in the cage.

[0070] In a further embodiment of the present invention, the distance between the front and rear car blockers 6 and 7 is not less than the wheel spacing of the empty mine car 11 placed on the push rail 3, and is less than the wheel spacing between the end wheels of two adjacent empty mine cars 11. Sufficient space is left for the front mine car.

[0071] Example 7: In a further embodiment of this solution, a safety door 10 is provided on both the infeed track 3 and the ejection track 4 facing the cage 1. The bottom end of the safety door 10 is spaced apart from the cradle 5. Signals are sent only after the cradle 5 and the safety door 10 are fully opened and closed. The hydraulic lever 801 motor is activated to either move the empty mine car 11 into the cage 1 or to move the head shunting section to the rear of the next empty mine car 11. The hoist then operates to lower the cage 1 (this is when the cradle 5 and the safety door 10 are fully closed).

Any technician familiar with the technical field within the technical scope disclosed by the present invention can make equivalent replacements or changes based on the technical solution and utility model concept of the present invention, which should be covered by the protection scope of the present invention.
