Description

Technical Field

[0001] This utility model belongs to the technical field of vertical shaft engineering construction equipment, and in particular, it is a multi-functional platform for lifting vertical shaft slag removal equipment. Background Technology

[0002] In shaft construction, the efficiency and safety of muck removal operations are crucial factors affecting project progress and construction quality. Currently, commonly used muck removal lifting platforms have the following shortcomings:

[0003] 1. Poor structural versatility, mostly simple steel frame assembly or welding, not customized for the size and stress characteristics of the slag removal equipment, cumbersome connection methods, easy to shake during hoisting or operation, posing safety hazards.

[0004] 2. Limited operating range: Small muck loaders are limited by the lifting position and can only operate in a local area. They cannot cover the entire cross section and need to be frequently adjusted, resulting in low efficiency and blind spots.

[0005] The operation process is lengthy. The chute cover needs to be temporarily opened during slag removal, leaving gaps in the wellhead protection. Furthermore, the repeated opening and closing of the cover during process transitions is cumbersome and time-consuming, easily causing construction delays. 3. Slag removal efficiency is limited. For example, the fixed-hole-spacing slag removal equipment lifting platform disclosed in Chinese utility model patent publication number CN 206680081 U is prone to clogging due to its fixed-hole-spacing design. It is difficult to accommodate slag of different particle sizes, requiring frequent cleaning and affecting continuous operation. Summary of the Invention

[0006] The technical problem to be solved by this utility model is to provide a multi-functional platform for lifting equipment for vertical shaft slag removal. It can solve the shortcomings of existing platforms in terms of structural adaptability, ease of operation, operational safety and slag removal efficiency. It can be quickly connected, cover the entire cross section, simplify the process and has both safety and high efficiency in slag removal.

[0007] The technical solution adopted in this utility model is as follows:

[0008] A multi-functional platform for lifting vertical shaft slag removal equipment includes multiple horizontal beams and longitudinal beams. The horizontal beams and longitudinal beams are welded perpendicularly to each other to form a "well"-shaped frame. Each horizontal beam and longitudinal beam has a support leg welded to both ends, and a slag discharge port is formed between adjacent support legs. Lifting lugs are symmetrically welded to the outer side of each horizontal beam. Each longitudinal beam has a platform pin connection port on its top surface, and an equipment pin connection port is correspondingly welded to the wheel frame on the side of the slag removal equipment. The platform pin connection port and the equipment pin connection port are connected by a "["-shaped connecting pin, and a fixing nut assembly is provided at the end of the connecting pin.

[0009] Preferably, multiple diagonal braces are welded at the cross joints of the "well" shaped frame.

[0010] Preferably, multiple anti-slip steel bars are welded at equal intervals on the top surface of each beam.

[0011] Preferably, there are two horizontal beams and two vertical beams, which are parallel and symmetrical to form a "well" shaped frame.

[0012] Preferably, there are two diagonal braces, arranged in an X-shape at the cross nodes of the frame.

[0013] Preferably, the outrigger height is not less than 0.5m.

[0014] Preferably, the anti-slip reinforcement is a threaded steel bar with a diameter of not less than 10mm, and is evenly arranged along the length of the top of the beam at a spacing of not more than 200mm, with the length of the reinforcement bar being consistent with the width of the top of the beam.

[0015] The multi-functional platform for lifting muck removal equipment in vertical shafts provided by this utility model has the following advantages:

[0016] 1. Effectively solve the technical problems of poor versatility, low operating efficiency and high safety risks of existing vertical shaft muck removal equipment lifting platforms, and provide a multi-functional platform with reasonable structure, integrated functions and strong adaptability.

[0017] 2. The platform employs a "well"-shaped frame with cross-bracing and I-beams to ensure overall rigidity and load-bearing capacity. Symmetrically distributed legs create an open slag discharge space, significantly improving slag discharge efficiency. Simultaneously, the platform covers the slag chute opening, preventing frequent opening and closing and reducing the risk of personnel falling. Top anti-slip steel bars and symmetrical lifting lugs constitute a safe and reliable lifting structure. Utilizing a "[-type connecting pin + fixing nut" fixing structure, the slag removal equipment and platform are quickly and rigidly connected, significantly improving the lifting and operational safety of the slag removal equipment.

[0018] 3. Integrating four major functions—lifting, fixing, anti-slip, and slag removal—it effectively solves the problems of poor versatility, low operating efficiency, and high safety risks of existing vertical shaft slag removal platforms. It realizes the upgrade and transformation of vertical shaft slag removal operations from "partial manual intervention" to "full mechanization," significantly improving the lifting safety and construction efficiency of vertical shaft slag removal equipment.

[0019] With its simple structure, convenient manufacturing, easy operation, efficient slag removal, safety and reliability, economic practicality, and low cost, it is suitable for various vertical shaft engineering construction sites and has broad prospects for promotion and application.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0033] like Figures 1-8 As shown, a multi-functional platform for lifting vertical shaft slag removal equipment includes multiple horizontal beams 1 and longitudinal beams 2. The multiple horizontal beams 1 and longitudinal beams 2 are welded perpendicularly to each other to form a "well"-shaped frame. Each horizontal beam 1 and longitudinal beam 2 has a support leg 4 welded to both ends, and a slag discharge port 11 is formed between adjacent support legs 4. Lifting lugs 6 are symmetrically welded to the outer side of each horizontal beam 1. Each longitudinal beam 2 has a platform pin connection port 7 on its top surface, and an equipment pin connection port 9 is welded to the wheel frame on the side of the slag removal equipment 8. The platform pin connection port 7 and the equipment pin connection port 9 are connected by a "["-shaped connecting pin 10, and a fixing nut assembly is provided at the end of the connecting pin 10.

[0034] The "well" shaped frame has multiple diagonal braces welded at the intersection of its frames.

[0035] Multiple anti-slip steel bars 5 are welded at equal intervals on the top surface of each beam 1.

[0036] There are two beams, 1 horizontal and 2 vertical, which are parallel and symmetrical to form a "well" shaped frame.

[0037] There are two diagonal braces 3, which are arranged in an X-shape at the frame intersections to enhance the lateral and longitudinal stiffness of the frame.

[0038] The height of outrigger 4 shall not be less than 0.5m, which can be determined according to the size of the blasted rock fragments.

[0039] The crossbeam 1, longitudinal beam 2, diagonal brace 3, and support leg 4 are all made of I-beams of size I20 or larger.

[0040] The anti-slip reinforcement 5 is a threaded steel bar with a diameter of not less than 10mm, and is evenly arranged along the top length of the crossbeam 1 at a spacing of not more than 200mm. The length of the steel bar is consistent with the top width of the crossbeam 1.

[0041] There are four lifting lugs 6 in total, which are symmetrically welded to the outer ends of the two crossbeams 1 at a position of 200-300mm. The lifting lugs 6 are made of steel plates with a thickness of not less than 20mm, and the inner diameter of the lugs matches the lifting hook.

[0042] There are four platform pin connection ports 7 and four equipment pin connection ports 9, arranged in a one-to-one correspondence. The inner diameter of the reserved circular connection port matches the outer diameter of the connection pin 10.

[0043] Platform pin connector 7 and equipment pin connector 9 are welded from steel plates with a thickness of not less than 10mm.

[0044] The connecting pin 10 is made of round steel with a diameter of not less than 25mm, the end thread length is not less than 50mm, and it forms a "[" shaped bending structure.

[0045] This utility model employs a grid-shaped frame formed by vertically welding horizontal beams 1 and vertical beams 2, reinforced with cross diagonal braces 3 and made of I-beams, ensuring the overall rigidity and load-bearing capacity of the platform frame. Symmetrically distributed support legs 4 form an open slag discharge port 11, greatly improving slag discharge efficiency; simultaneously, the platform covers slag chute 12, avoiding frequent opening and closing of the chute openings and reducing the risk of personnel falling. Top anti-slip steel bars 5 and symmetrical lifting lugs 6 constitute a safe and reliable lifting structure. The platform pin connection port 7 and the equipment pin connection port 9 utilize a "[-type connecting pin 10 + fixing nut" fixing structure to achieve rapid and rigid connection between the slag removal equipment 8 and the platform, significantly improving the lifting and operational safety of the slag removal equipment.

[0046] like Figure 9 As shown, the working process of this utility model is as follows:

[0047] In use, firstly, the crane hook is connected to the platform lifting lug 6, and the entire platform is placed directly above the slag chute 12 of the vertical shaft 13. After adjusting the level, the bottom of the outrigger 4 contacts the hardened ground around the well opening to form a stable support. Then, the slag removal equipment 8 is hoisted to the designated position on the platform, the platform pin connection port 7 is aligned with the equipment pin connection port 9, the [type connecting pin 10 is inserted, and the fixing nut is tightened to complete the rigid connection and fixation between the platform and the slag removal equipment 8.

[0048] During the operation, the cross-section of the vertical shaft 13 is excavated by the slag removal equipment 8. The slag produced during the excavation will fall from the slag chute 12 to its bottom through the slag discharge port 11 formed between the adjacent support legs 4, thereby realizing the slag discharge operation.

[0049] After the operation is completed, the platform is hoisted to the hardened ground around the shaft opening of vertical shaft 13, the nuts are loosened, the connecting pins 10 are pulled out, the slag removal equipment 8 is lifted off the platform, and the platform is transported to the next working face.

The protection scope of this utility model should be defined as the technical solution described in the claims, including equivalent substitutions of the technical features described in the claims. That is, equivalent substitutions and improvements within this scope are also within the protection scope of this utility model.
