Description

Technical Field

[0001] This utility model relates to the field of underground transportation technology, specifically, to a trackless transportation system for pressure steel pipes suitable for small-section, large-angle circular inclined shafts. Background Technology

[0002] The installation of pressure steel pipes in small-section circular inclined shafts is limited by the small cross-sectional size of the excavation and the circular shape of the tunnel. Pressure steel pipes are generally transported by rail. During the process, due to the high likelihood of deviations during excavation, the installation and transportation of pressure steel pipes in long inclined shafts are prone to derailment.

[0003] At the same time, the steeply inclined circular tunnels make it inconvenient for people to go up and down, and are difficult to handle after derailment, posing a great safety hazard.

[0004] Moreover, the difficulty and cost of laying the tracks are relatively high.

[0005] In summary, using rail transport requires a huge investment of manpower and materials to install the rails, and the high-altitude work during the rail installation process increases the construction safety risks and construction costs.

[0006] To solve the aforementioned technical problems, it is necessary to develop a transportation device that is lower in cost and relatively safer to address the issue of transporting pressure steel pipes in small-section, high-angle circular inclined shafts. Utility Model Content

[0007] The purpose of this invention is to address the shortcomings of existing technologies by providing a trackless transport system for pressure steel pipes that is lower in cost and higher in safety, suitable for small-section, large-angle circular inclined shafts.

[0008] To achieve the above objectives, the technical solution adopted by this utility model is: a trackless transport system for pressure steel pipes suitable for small-section, large-angle circular inclined shafts, including a large-angle circular inclined shaft, a transport trolley, a winch, a wire rope, and a first hand-operated hoist;

[0009] The wheels of the transport trolley are inclined wheels with the wheel face tilted outwards, and the inclined wheels are used to roll in cooperation with the well surface of the large-angle circular inclined well;

[0010] Fixed lifting lugs are provided on both sides of the upper end face of the transport trolley. The first hand chain hoist, in conjunction with the fixed lifting lugs, is used to load and fix the pressure steel pipe onto the transport trolley.

[0011] The front end of the transport trolley is provided with a traction lug, which is used to connect to the traction end of the wire rope;

[0012] The winch is located at the top of the inclined circular shaft with a large inclination angle, and the force-bearing end of the winch is connected to the force-bearing end of the wire rope.

[0013] Preferably, the transport trolley has 4-8 inclined wheels, and the inclination angle of the inclined wheels is 30°-45°.

[0014] Preferably, the transport trolley includes a pallet welded from I-beams, and the inclined wheels, fixed lugs, and traction lugs are all welded and fixed to the transport trolley.

[0015] Preferably, an installation space is provided on the horizontal side of the top of the large-angle circular inclined shaft, and the winch is installed in the installation space to make way for the transport trolley.

[0016] Preferably, a plurality of guide wheels are provided at the top corner of the inclined circular shaft with a large inclination angle, and the guide wheels are used to guide the wire rope.

[0017] Preferably, an auxiliary lifting lug is provided at the top of the front end of the pressure steel pipe, and a second hand chain hoist is provided between the auxiliary lifting lug and the wire rope.

[0018] Preferably, the number of fixed lifting lugs is set in multiple sets, and they are evenly distributed along the length of the transport trolley.

[0019] Preferably, a reversing wheel is provided between the winch and the guide wheel.

[0020] Preferably, there are two traction lugs, symmetrically arranged at the front end of the transport trolley.

[0021] Preferably, the transport trolley has 8 inclined wheels, and the inclination angle of the inclined wheels is 30°.

[0022] This utility model has substantial features and progress compared to the prior art. Specifically, this utility model eliminates the work of laying tracks inside a large-angle circular inclined shaft, saving construction time and costs. It uses a traction mechanism composed of a winch, wire rope and transport trolley to traction and lift the transport trolley to transport the pressure steel pipe to the designated position. No human intervention is required in the intermediate transportation process, which is safer and more cost-effective.

[0023] Furthermore, to avoid deviation, a transport trolley with inclined wheels is used. With the support of the inclined wheels, the entire trolley can stay centered and not deviate.

[0024] Furthermore, guide wheels are installed to ensure the straightness of the steel wire rope used for traction, thereby preventing the transport trolley from deviating. Attached Figure Description

Detailed Implementation

[0030] The technical solution of this utility model will be further described in detail below through specific embodiments.

[0031] like Figures 1-4 As shown, a trackless transport system for pressure steel pipes suitable for small-section, large-angle circular inclined shafts includes a large-angle circular inclined shaft 1, a transport trolley 2, a winch 3, a wire rope 4, a guide wheel 5, a first hand chain hoist 6, and a second hand chain hoist 7.

[0032] The wheels of the transport trolley 2 are inclined wheels 8 with the wheel surface tilted outward. The inclined wheels 8 are used to roll and cooperate with the well surface of the large-angle circular inclined well 1. In cross-section, the inclined wheels 8 are distributed in a figure-eight shape, with a quantity of 4-8 and an inclination angle of 30°-45°. In this embodiment, it is designed to have 8 wheels with an inclination angle of 30°. The material is a wide steel wheel. Under the inclination angle, it can effectively support the surface of the large-angle circular inclined well and keep the middle position of the transport trolley 2 from shifting.

[0033] The transport trolley 2 is made of I-beam steel plates welded together, and the inclined wheels, fixed lugs and traction lugs are all welded and fixed to the transport trolley.

[0034] The upper end face of the transport trolley 2 is provided with fixed lifting lugs 9 on both sides, in multiple sets, and distributed at equal intervals along the length of the trolley. The first hand chain hoist 6, together with the fixed lifting lugs 9, is used to load and fix the pressure steel pipe 11 on the transport trolley 2, that is, to fix the pressure steel pipe 11 on the transport trolley 2 by binding.

[0035] The front end of the transport trolley 2 is provided with a traction lug 10, which is used to connect with the traction end of the wire rope 4. Specifically, in this embodiment, there are two traction lugs 10, which are symmetrically arranged at the front end of the transport trolley 2 to make the traction force distribution even.

[0036] The winch 3 is located at the top of the inclined circular shaft 1 with a large angle. The force-bearing end of the winch 1 is connected to the force-bearing end of the wire rope 4. During installation, due to the limited space of the inclined circular shaft 1 with a large angle, in order to make room for the transport trolley to move, an installation space 12 needs to be set on the horizontal side of the top of the inclined circular shaft 1 with a large angle. The winch 3 is installed in the installation space 12 to make way for the transport trolley 2.

[0037] Since the installation position of the winch 3 is not in the center of the well, it is necessary to control the direction of the wire rope 4. Several guide wheels 5 are provided at the top corner of the large-angle circular inclined well. The guide wheels 5 are used to guide the wire rope 4. A reversing wheel 14 is provided between the winch 3 and the guide wheels 5 to reverse the direction.

[0038] Meanwhile, since the center of gravity of the pressure steel pipe is relatively high during transportation, an auxiliary lifting lug 13 is provided at the top of the front end of the pressure steel pipe 11. A second hand-operated hoist 7 is provided between the auxiliary lifting lug 13 and the wire rope 4, so that the transport trolley and the pressure steel pipe 11 are as a whole, and the force is more stable and balanced.

[0039] Using this system, the pressure steel pipe 11 can be transported from the bottom to the top of the inclined circular shaft 1 at a large angle quickly, safely and efficiently, which facilitates construction and installation, greatly shortens the construction cycle and significantly reduces costs.

[0040] Finally, it should be noted that: the preferred embodiments of this patent have been described in detail above, but this patent is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of this patent.
