Description

Technical Field

[0001] The invention relates to the technical field of engineering transportation, and in particular to a transport trolley for inclined shaft excavation. Background Art

[0002] Inclined shaft is a common structure in water conservancy and hydropower projects. The excavation of inclined shaft has always been a difficult point in engineering construction, especially the transportation of construction machinery. At present, the excavation of inclined shaft mainly adopts the pilot shaft method, that is, first use a reverse drilling rig to drill a hole to form a pilot shaft, and then blast and excavate, and the excavated slag is discharged from the pilot shaft.

[0003] In traditional inclined shaft excavation construction, since mechanical equipment such as backhoe excavators cannot be transported to the inclined shaft face, the inclined shaft excavation slag is often removed manually. Manual slag removal is inefficient and has high safety risks. Although the use of mechanical equipment such as backhoe excavators for slag removal is the best solution, how to transport the backhoe excavator from the inclined shaft entrance to the excavation face has always been a problem that plagues engineering construction. The main problems faced by the transportation of backhoe excavators are as follows: One is the problem of transporting the backhoe excavator. The space in the underground buried inclined shaft is small, and the backhoe excavator cannot be loaded into the transport vehicle using a lifting machinery.

[0004] The second issue is how the backhoe excavator drives out of the tunnel face from the transport cart. Since the tunnel face of the inclined shaft excavation gradually descends with the excavation and blasting cycle, and the track of the transport cart can only be laid to the tunnel face of the cycle before the current blasting, after the current blasting, the track of the cart is still 2 to 3 meters away from the tunnel face, and the backhoe cannot be transported to the excavation tunnel face. Summary of the invention

[0005] The purpose of the present invention is to provide a transport trolley for inclined shaft excavation, use rails and the transport trolley as transportation tools, and then use machinery such as backhoe excavators to replace traditional manual slag removal construction methods, so as to improve construction efficiency and reduce safety risks.

[0006] In order to solve the above technical problems, the technical solution adopted by the present invention is: A transport trolley for inclined shaft excavation comprises a track installed in the inclined shaft, and also comprises a transport trolley, an inclined bracket is installed on the rear end of the transport trolley, a pulley assembly is provided on the inclined bracket, and the transport trolley is erected on the track through the pulley assembly; the front and rear ends of the transport trolley are both provided with openings, and the bottom of the transport trolley is a bearing platform; it also comprises a steel gantry, which is erected at the entrance of the inclined shaft, and a first guide wheel is installed on the top of the steel gantry; it also comprises a winch and a steel wire rope, one end of the steel wire rope is connected to the winch, and the other end of the steel wire rope is connected to the transport trolley after passing around the first guide wheel.

[0007] Preferably, the pulley assembly comprises a front pulley block and a rear pulley block, the front pulley block is mounted on the lower end of the inclined surface of the inclined bracket, and the rear pulley block is mounted on the upper end of the inclined surface of the inclined bracket.

[0008] Preferably, the front pulley block includes a front wheel axle installed on the inclined bracket, a pulley mounting frame is hinged on the front wheel axle, and the front and rear ends of the pulley mounting frame are respectively installed with first running wheels; the rear pulley block includes a rear wheel axle installed on the inclined bracket, and the rear wheel axle is installed with a second running wheel.

[0009] Furthermore, a trolley loading platform is fixedly installed under the steel gantry, and the trolley loading platform is used to dock with the bearing platform.

[0010] Furthermore, the bearing platform is provided with two or more steel plate interfaces on both sides thereof; and also includes a traveling steel plate, one end of which is detachably connected to the steel plate interface.

[0011] Furthermore, it also includes a second guide wheel, which is installed between the winch and the first guide wheel, and the middle part of the wire rope passes around the second guide wheel.

DETAILED DESCRIPTION

[0019] The technical scheme in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present invention, so as to have a further understanding of the concept of the present invention, the technical problems solved, the technical features constituting the technical scheme and the technical effects brought about.

[0020] like Figure 1 , Figure 2 , Figure 3 As shown, a transport trolley 1 for inclined shaft excavation includes a track 16 installed in the inclined shaft, and also includes a transport trolley 1, an inclined bracket 2 is installed on the rear end of the transport trolley 1, and a pulley assembly is provided on the inclined bracket 2, and the transport trolley 1 is erected on the track 16 through the pulley assembly; the front and rear ends of the transport trolley 1 are both provided with openings, and the bottom of the transport trolley 1 is a bearing platform 6; it also includes a steel gantry, the steel gantry is erected at the entrance of the inclined shaft, and a first guide wheel 13 is installed on the top of the steel gantry; it also includes a winch 10 and a wire rope 11, one end of the wire rope 11 is connected to the winch 10, and the other end of the wire rope 11 is connected to the transport trolley 1 after passing around the first guide wheel 13.

[0021] The rear end of the transport trolley 1 in the present invention is equipped with an inclined bracket 2, and the pulley assembly of the inclined bracket 2 is connected to the track 16 in the inclined shaft, so that the transport trolley 1 is driven on the track 16 of the inclined shaft. After the transport trolley 1 is erected on the track 16, a winch 10 for lifting the transport trolley 1 is selected according to the load of the trolley. The winch 10 is fixedly installed outside the entrance of the inclined shaft, and the output end of the winch 10 is connected to the wire rope 11. The wire rope 11 passes around the first guide wheel 13 on the top of the steel gantry and is connected to the transport trolley 1. After the connection, the winch 10 is used to control the lifting and lowering movement of the transport trolley 1 on the track 16, and then the transport trolley 1 is used as a transportation device to transport the backhoe excavator 15.

[0022] like Figure 4 , Figure 5As shown, the transportation process of the backhoe excavator 15 is as follows: the transport trolley 1 is fixed on the top of the track 16, that is, fixed at the entrance position of the inclined shaft, by the pull of the winch 10 and the wire rope 11, and the backhoe excavator 15 is driven onto the transport trolley 1 to complete the preliminary work. Then the transport trolley 1 and the backhoe excavator 15 are lowered to the face along the track 16 by the winch 10, and the backhoe excavator 15 drives out of the transport trolley 1 from the side of the transport trolley 1 to carry out the slag removal operation on the face. After the slag removal operation is completed, the transport trolley 1 and the backhoe excavator 15 are transported back as a whole by the winch 10 to discharge the slag. The track 16 and the transport trolley 1 are used as transportation tools, and then the backhoe excavator 15 and other machines are used to replace the traditional manual slag removal construction method, thereby improving the construction efficiency. The backhoe excavator 15 completes the slag removal and avoids manual slag removal on the face of the inclined shaft, which can reduce safety risks.

[0023] Preferably, the pulley assembly includes a front pulley block and a rear pulley block 3 , the front pulley block is installed at the lower end of the inclined surface of the inclined bracket 2 , and the rear pulley block 3 is installed at the upper end of the inclined surface of the inclined bracket 2 .

[0024] Preferably, the front pulley block includes a front wheel shaft 8 mounted on the inclined bracket 2, a pulley mounting frame is hinged on the front wheel shaft 8, and the front and rear ends of the pulley mounting frame are respectively mounted with a first running wheel; the rear pulley block 3 includes a rear wheel shaft 7 mounted on the inclined bracket 2, and the rear wheel shaft 7 is respectively mounted with a second running wheel. The rear pulley block 3 is a pulley of conventional structure, and the front pulley block is respectively mounted with a first running wheel at the front and rear ends through the pulley mounting frame, so that the front pulley block can adjust its own angle according to the bending condition of the track 16, and the transport trolley 1 is smoother during operation and has less wear. The angle of the inclined shaft will not change greatly, and the transport trolley 1 can ensure that the backhoe excavator 15 always remains stable during transportation, ensuring the safety of the transportation process. When the angle of the inclined shaft has a certain curvature, at the curved track position, the front pulley block adjusts the horizontality of the transport trolley 1 itself after adapting to the bending angle, and ensures that the backhoe excavator 15 on the transport trolley 1 remains horizontal while ensuring that the lifting process is slow and stable, ensuring safety.

[0025] Furthermore, a trolley loading platform 14 is fixedly installed under the steel gantry, and the trolley loading platform 14 is used to dock with the carrying platform 6. The trolley loading platform 14 is arranged to dock with the carrying platform 6, so that when the transport trolley 1 is parked at the entrance of the inclined shaft, the backhoe excavator 15 can be driven directly from the trolley loading platform 14 to the carrying platform 6. The trolley loading platform is arranged under the steel gantry, so that the backhoe excavator 15 can be driven out from the front of the transport trolley without adjusting the direction after being transported to the bottom of the inclined shaft, which is convenient for working in a narrow space.

[0026] Furthermore, the two sides of the bearing platform 6 are respectively provided with more than two steel plate interfaces 9; and the bearing platform 6 also includes a traveling steel plate 5, one end of which is detachably connected to the steel plate interface 9. The steel plate interface 9 is provided on both sides of the bearing platform 6. Under normal conditions, it is most convenient for the backhoe excavator 15 to drive out from the front end of the transport trolley 1 after driving into the transport trolley 1 from the rear end of the transport trolley 1. Considering that there are many situations in the face of the inclined shaft, setting up steel plate interfaces to allow the backhoe excavator 15 to drive out from both sides can better judge according to the on-site situation of the face, and choose a better position to drive out the backhoe excavator 15 to complete the excavation. Secondly, the backhoe excavator 15 that has completed the slag removal work can also have more choices in the process of driving back to the bearing platform 6.

[0027] Furthermore, it also includes a second guide wheel 12, which is installed between the winch 10 and the first guide wheel 13, and the middle part of the wire rope 11 passes around the second guide wheel 12. The second guide wheel 12 is set more to adjust the angle of the wire rope 11, so that the force direction of the wire rope at the first guide wheel 13 is better; secondly, the second guide wheel 12 also provides another force point and limit point for the wire rope 11, and the wire rope 11 itself will not swing due to the excessive length of the connection point, thereby improving the stability of the winch 10 when working. After the second guide wheel 12 is set, the end of the wire rope 11 connected to the winch 10 can be close to the ground, leaving space, and will not affect the backhoe excavator 15 from entering the transport vehicle 1.
