Description

Technical Field

[0001] This utility model relates to the field of building construction technology, specifically to a lifting construction platform for pipe jacking construction. Background Technology

[0002] With the rapid development of national urbanization, the drainage system of municipal road planning has been gradually improved, and the pipe diameter and burial depth have been gradually increased. The previous open-cut trenching construction process is too deep and the volume is too large. Considering factors such as cost, quality, safety, environmental protection and impact on existing roads, for pipeline laying projects exceeding a certain depth, the pipe jacking construction process is superior to the open-cut trenching construction process in all aspects.

[0003] During pipe jacking, frequent hoisting and transportation of goods between the ground and the shaft are required. This necessitates the erection of a fixed hoisting platform and a construction platform for manual transport along the upper edge of the pipe jacking shaft. Traditional working platforms for pipe jacking shafts typically use on-site brickwork structures, which are unstable. The platforms are usually constructed by laying crossbeams and then adding wooden formwork, resulting in low efficiency and safety hazards. The hoisting and protective systems are installed on-site by construction workers. The entire platform is mostly a temporary structure, leading to cumbersome installation, low reuse rate, immobility, poor safety and stability, material waste, and slow construction. In cases involving multiple pipe jacking shafts and jacking segments, the construction process requires frequent construction, erection, dismantling, and rebuilding of the working platform, further extending the construction period and increasing costs.

[0004] Therefore, it is necessary to study a lifting platform for pipe jacking construction. Utility Model Content

[0005] Therefore, the purpose of this utility model is to provide a lifting platform for pipe jacking construction, which can effectively solve the problems that existing lifting platforms for pipe jacking construction are mostly temporary structures with poor reusability, and require frequent masonry, erection, demolition and dismantling during the construction process, resulting in low construction efficiency and increased costs.

[0006] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0007] A lifting platform for pipe jacking construction includes a support frame, a working platform, a gantry frame, a gantry beam, an electric hoist lifting device, and a counterweight; the front end of the support frame is used to be mounted on the upper edge of the pipe jacking shaft.

[0008] The work platform is horizontally fixed to the top of the support frame, and multiple sets of lifting rings are fixed to the edge of the work platform;

[0009] The front and rear ends of the gantry frame are respectively fixedly mounted on the front and rear ends of the support frame. The two sets of gantry frames together support a gantry beam, which is located in the middle of the support frame. The front and rear ends of the gantry beam extend out of the working platform in the front and rear directions respectively.

[0010] The front end of the gantry crane beam is located directly above the pipe jacking shaft;

[0011] The front end of the gantry crane beam is equipped with an electric hoist lifting device, and the rear end of the gantry crane beam is equipped with a counterweight.

[0012] Furthermore, the gantry frame includes a fixed frame and a reinforcing frame, both of which are portal-shaped. The tops of the fixed frame and the reinforcing frame are fixedly connected to the gantry beam, the bottom of the fixed frame is fixedly connected to the support frame, and the bottom of the reinforcing frame is fixedly connected to the middle of the fixed frame, forming a triangular support structure.

[0013] Furthermore, the gantry beam is I-shaped, the hoist lifting device is movably mounted on the lower edge plate of the gantry beam, and the gantry frame is fixedly connected to the top of the gantry beam.

[0014] Furthermore, multiple connecting rods are fixedly installed at intervals along the front-to-back direction on the top of the gantry beam, and a top frame is erected and fixed together on the top of the connecting rods along the front-to-back direction.

[0015] Furthermore, the connecting rod and the top frame are each arranged in two sets symmetrically on the left and right, and a sunshade is fixedly laid on the top frame.

[0016] Furthermore, a protective railing is fixedly installed around the support frame, surrounding the work platform, and a protective net is installed on the railing.

[0017] Furthermore, the guardrail has an entrance / exit on its side, and the support frame has a ladder on its side, with the ladder corresponding to the entrance / exit position.

[0018] The beneficial effects of the above technical solution are:

[0019] This utility model horizontally fixes the working platform to the top of the support frame, and the edge of the working platform is fixed with multiple sets of lifting rings. It can be assembled at a site other than the construction site and then hoisted and transported as a whole to different pipe jacking shafts by a crane. There is no need to repeatedly build and dismantle temporary structures on site, which significantly improves deployment efficiency and structural stability. It has good reusability and overcomes the problems of existing lifting platforms for pipe jacking construction being mostly temporary structures with poor reusability and requiring frequent masonry, erection, demolition and dismantling during the construction process. It can effectively improve construction efficiency and construction costs.

[0020] The front end of the support frame is erected on the upper edge of the pipe jacking shaft, providing a reliable working platform for workers to move materials and operate the electric hoist lifting device. The gantry frame is fixedly erected at the front and rear ends of the support frame, with the gantry beam running through it and extending forward and backward. The front end of the gantry beam is located directly above the pipe jacking shaft, providing a reliable lifting point for the electric hoist lifting device set at the front end. A counterweight is set at the rear end to effectively ensure the balance of front and rear torques during operation, ensuring the structural stability and reliability of the platform during lifting.

Detailed Implementation

[0024] The present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments:

[0025] This embodiment aims to provide a lifting platform for pipe jacking construction, which is mainly used in pipe jacking construction technology. It addresses the problems that existing lifting platforms for pipe jacking construction are mostly temporary structures, inefficient, and pose safety hazards.

[0026] A type of lifting platform for pipe jacking construction, such as Figure 1 and Figure 2 It includes a support frame 1, a working platform 2, a gantry frame 3, a gantry beam 4, an electric hoist lifting device 5, and a counterweight 6.

[0027] Support frame 1 consists of multiple standardized steel frame units, each 2 meters long, connected by high-strength bolts. The legs of support frame 1 are fitted with pads.

[0028] The working platform 2 is horizontally fixed on the top of the support frame 1. The working platform 2 includes a main keel, a secondary keel, and a panel. The main keel is made of Q235-40x60 square tube, forming a space frame structure with a spacing of 0.9m. The secondary keel is made of 40x60 square timber, with a spacing of 0.3m, subdividing the main keel space frame structure. The panel is made of 15mm thick template. All components of the working platform 2 are made from leftover materials from the construction of the main structure of the pipe jacking well.

[0029] Multiple lifting rings 7 are fixed to the edge of the working platform 2, and these rings are fixed to the main keel for overall lifting. The working platform 2 can be lifted to the working position using a crane before or after the installation of the gantry frame 3, gantry beam 4, electric hoist lifting device 5, and counterweight 6. The bottom of the outriggers is then anchored into the working shaft ring beam using high-strength bolts, enabling the working platform 2 to be reused. This avoids the complexity of building a temporary platform on-site, significantly improving the efficiency of installation and dismantling. Compared to traditional temporary platforms built on-site, the pre-built structure is more stable and standardized. The front end of the support frame is used to support the upper edge of the pipe jacking shaft, providing a reliable working platform for workers to move materials and operate the electric hoist lifting device.

[0030] The gantry frame 3 has a fixed frame 401 located at the front and rear ends of the support frame 1. The gantry frame 3 includes a fixed frame 401 and a reinforcing frame 402. Figure 2 Both the fixed frame 401 and the reinforcing frame 402 are gantry-shaped to facilitate the passage of hoisted goods. Both the fixed frame 401 and the reinforcing frame 402 are secured using steel pipe binding. The bottom of the fixed frame 401 is fixedly connected to the support frame 1, and the bottom of the reinforcing frame 402 is fixedly connected to the middle of the fixed frame 401, forming a triangular support structure. The tops of both the fixed frame 401 and the reinforcing frame 402 are fixedly connected to the gantry beam 4, allowing the two sets of gantry frames 3 to jointly support a single gantry beam.

[0031] The gantry beam is located in the middle of the support frame 1. The gantry beam is I-shaped, with working platforms 2 extending from its front and rear ends in the front and rear directions, respectively. An electric hoist lifting device 5 is installed at the front end of the gantry beam 4. The gantry frame 3 is fixedly connected to the top of the gantry beam 4, so that the lower edge plate of the gantry frame 3 forms a continuous moving track for the electric hoist lifting device 5. This allows the electric hoist lifting device 5 to move and be positioned on the lower edge plate of the gantry beam 4. Specifically, the electric hoist lifting device 5 is equipped with electric moving wheels, enabling it to lift and move along the gantry frame 3. The specific structure and working principle of the electric hoist lifting device 5 utilize existing technology and will not be elaborated here.

[0032] The front end of the gantry beam 4 is located directly above the pipe jacking shaft, providing a reliable lifting point for the electric hoist lifting device 5 installed at the front end; the rear end of the gantry beam 4 is equipped with a counterweight 6 to balance the load when the electric hoist lifting device 5 lifts goods and prevents overturning.

[0033] like Figure 1 Multiple connecting rods 8 are welded and fixed at intervals along the front-to-back direction on the top of the gantry beam. A top frame 9 is erected and fixed along the front-to-back direction on the top of the connecting rods 8. Figure 2The connecting rod 8 and the top frame 9 are symmetrically arranged in two sets. The top frame 9 is fixedly covered with a sunshade 10. The sunshade 10 is located above the operating area of ​​the electric hoist lifting device 5 to provide sunshade during worker operation.

[0034] A protective railing 11 is fixedly installed around the support frame 1. The protective railing 11 surrounds the work platform 2 and is tied to the support legs of the support frame 1. A protective net 12 is installed on the protective railing 11. The protective net 12 is made of dense mesh to form a safety protection.

[0035] The guardrail 11 has an entrance / exit 13 on its side, and the support frame 1 has a ladder 14 on its side. The ladder 14 is positioned corresponding to the entrance / exit 13 so that workers can enter the work platform 2.

[0036] Before use, the support frame 1 and the working platform 2 can be assembled in an area outside the construction site. Then, the working platform 2 is hoisted to the construction position by a crane, so that the front end of the support frame is set on the upper edge of the jacking shaft. The bottom of the outriggers is fixedly connected to the working shaft ring beam with high-strength bolts. Then, the gantry frame 3, gantry beam 4, electric hoist hoisting device, etc. are built on the working platform 2 with the help of the crane to form a complete construction platform.
