Description

Technical Field

[0001] This application belongs to the field of municipal construction technology, specifically relating to a mobile excavation platform for slag pits. Background Technology

[0002] In municipal engineering construction, such as deep foundation pit excavation and tunnel boring, a large amount of excavated soil often accumulates. Therefore, multiple excavated soil pits are needed to store the soil, preventing environmental pollution caused by indiscriminate dumping and facilitating subsequent resource utilization or compliant disposal. Currently, to facilitate the transfer of excavated soil from excavators to dump trucks, platforms need to be set up at each excavated soil pit for excavation.

[0003] While installing platforms at each spoil heap facilitates excavator transport of spoil, it significantly increases costs. For subway construction projects requiring 6-8 spoil heaps, platform installation alone costs 420,000-560,000 yuan, accounting for over 30% of the total spoil disposal cost. For example, actual measurements at a deep foundation pit project in Southwest China showed that the annual maintenance cost of a fixed platform reached 84,000 yuan, with equipment utilization less than 40%. Furthermore, the dispersed platform foundations damage the integrity of the spoil heap's impermeable layer; construction data shows that the slurry leakage rate under traditional methods is as high as 3.2 L / m²•d. A subway project in East China experienced groundwater pollution due to leakage at the joints of multiple platforms, with repair costs exceeding 2 million yuan. Utility Model Content

[0004] The purpose of this application is to provide a mobile excavation platform for slag pits, which requires only one platform to meet the needs of multiple slag pits to be moved back and forth, thus solving the problems of high cost, easy leakage and poor flexibility of traditional platforms.

[0005] The objective of this application is achieved through the following technical solution:

[0006] A mobile excavation platform for a slag pit includes a slag pit. At least two slide rails are provided at the opening of the slag pit. The slide rails are provided with grooves that are opposite to the adjacent slide rails. A platform plate that slides longitudinally is provided between the opposite grooves. The front and rear ends of the platform plate are respectively connected to traction equipment on the ground by traction ropes.

[0007] Furthermore, the aforementioned slag pit has a rectangular structure, and adjacent slag pits are separated by partitions.

[0008] Furthermore, both the slide rail and the platform plate are made of steel.

[0009] Furthermore, the slide rails are arranged in two rows.

[0010] Furthermore, the slide rail is a single longitudinal beam.

[0011] Furthermore, the slide rail is a side longitudinal beam, and a middle longitudinal beam is arranged between the opposite side longitudinal beams, with a cross beam connecting the side longitudinal beams and the middle longitudinal beam.

[0012] Furthermore, an angle plate is provided at the connection between the side longitudinal beam and the middle longitudinal beam.

[0013] Furthermore, the slide is L-shaped, and both sides of the platform plate are L-shaped.

[0014] Furthermore, the upper surface of the platform plate is provided with anti-slip patterns.

[0015] Furthermore, both ends of the platform plate are connected to the side traction device via traction ropes.

[0016] Furthermore, the middle of both the front and rear ends of the platform plate are connected to the central traction device via traction ropes.

[0017] The beneficial effects of this application are:

[0018] (1) Social Benefit Prediction Analysis: The mobile platform reduces the area occupied by fixed cast-in-place concrete platforms, and is more flexible in terms of loading location, making it easier for excavators to reach some dead corners of the slag pits. The steel platform covers several tandem slag pits (8 meters deep) via sliding rails, and in conjunction with the tunnel boring machine's rhythm of 135 m³ of excavation per ring, it achieves seamless connection between slag loading and transportation, shortening the slag retention time compared to the traditional method of excavators traveling back and forth to dig and load. This mobile steel platform, through modular structure, intelligent control and dynamic adaptation design, reconstructs the slag transfer operation mode, significantly reducing the total life cycle cost while ensuring construction safety and environmental compliance, and to a large extent realizing civilized construction of slag loading in municipal engineering. In addition, the traditional method of building multiple construction platforms, with dispersed platform bases, damages the integrity of the slag pit's anti-seepage layer, which can easily lead to groundwater pollution. The construction of the steel mobile platform greatly reduces the damage to the slag pit's anti-seepage layer, reduces the probability of leakage, and thus meets the requirements of green construction.

[0019] (2) Economic Benefit Forecast Analysis: Traditional slag pit platforms require a separate concrete foundation for each slag pit (approximately 50,000 RMB / pit) and the installation of anti-slip steel plates (approximately 20,000 RMB / pit). In contrast, the steel mobile platform adopts a modular design, and it is estimated that only a one-time investment of approximately 200,000 RMB is needed to cover 6-8 slag pits, reducing initial investment costs by 60%-70%. Traditional concrete foundations are prone to cracking due to slag corrosion and load impact, with annual maintenance costs of approximately 84,000 RMB / 8 pits. The mobile platform uses Q345B high-strength steel and self-lubricating slide rails, and the annual maintenance cost is expected to be reduced to 32,000 RMB, a decrease of 61.9%.

[0020] The aforementioned main solution and its various further alternatives can be freely combined to form multiple solutions, all of which are solutions that can be adopted and claimed in this application; furthermore, the (non-conflicting alternatives) can also be freely combined with each other and with other alternatives. Those skilled in the art, after understanding this solution, will realize from the prior art and common general knowledge that there are many combinations, all of which are technical solutions to be protected in this application, and will not be exhaustively listed here.

Detailed Implementation

[0032] The present application will be further described below with reference to specific embodiments and accompanying drawings.

[0033] Example 1

[0034] refer to Figures 1-6As shown, a mobile excavation platform for a slag pit includes a slag pit 1, a slide rail 2, a chute 3, a platform plate 4, a traction rope 5, and a traction device 6.

[0035] The slag pit 1 is an open pit used for stockpiling slag. At least two sliding rails 2 are provided at the opening of the slag pit 1. The sliding rails 2 provide sliding support for the platform plate 4, ensuring the horizontal and longitudinal movement trajectory of the platform plate 4 and providing support for the platform plate 4, thus forming a stable support system.

[0036] The slide rail 2 is provided with a slide groove 3 opposite to the adjacent slide rail 2. A platform plate 4 that slides longitudinally is provided between the opposite slide grooves 3. The slide grooves 3 specifically support the sliding of the platform plate 4, that is, the slide grooves 3 guide the horizontal sliding of the platform plate 4 and support the platform plate 4 at the same time.

[0037] The front and rear ends of the platform plate 4 are connected to the traction device 6 on the ground by traction ropes 5. The traction device 6 retracts and releases the traction ropes 5. One end of the traction rope 5 is wound up, while the other end of the traction rope 5 is released, thereby driving the platform plate 4 to move.

[0038] The slag pit 1 is a rectangular reinforced concrete structure, which facilitates construction. Several slag pits 1 can be arranged, and adjacent slag pits 1 are separated by partitions 101, which are also made of reinforced concrete. Several slag pits 1 can realize the batch stacking or transfer of slag, which is convenient for construction.

[0039] Both the slide rail 2 and the platform plate 4 are made of steel, preferably Q345B high-strength steel, which has the capacity to support and bear the load of the platform plate 4 and the equipment on it, and is durable and can be reused multiple times. There are two slide rails 2, which are arranged exactly on the two long sides of the opening of the slag pit 1. The long sides of the slag pit 1 support the slide rails 2 without obstructing the opening of the pit, ensuring smooth construction.

[0040] In this embodiment, the slide rail 2 is a single longitudinal beam 201. The single longitudinal beam 201 is a single beam and is not connected to other beams. That is, the platform plate 4 is only supported by the single longitudinal beams 201 on both sides, which is suitable for scenarios with a small lateral span.

[0041] The slide 3 has an L-shaped structure, and both sides of the platform plate 4 have L-shaped structures. The L-shaped structure is used to lock the slide 3 and the platform plate 4 together, preventing the platform plate 4 from moving laterally, that is, preventing the platform plate 4 from falling out of the slide 3 and causing a safety accident.

[0042] Platform plate 4 supports the excavating equipment (excavator) and personnel to pour or excavate the excavated soil into or out of the excavated soil pit 1. The upper surface of platform plate 4 is provided with anti-slip patterns to increase the friction of the excavating equipment and personnel on platform plate 4 and achieve stable operation.

[0043] Both ends of the platform plate 4 are connected to the side traction device 601 via traction ropes 5. Stable driving of the platform plate 4 is achieved through uniform traction and pulling from both sides. The platform plate moves back and forth by a motor via steel wire ropes welded to both ends. The traction ropes 5 are made of steel wire ropes, and the traction device 601 is a winch.

[0044] Example 2

[0045] refer to Figures 6-10 As shown, a mobile excavation platform for a slag pit includes a slag pit 1, a slide rail 2, a chute 3, a platform plate 4, a traction rope 5, and a traction device 6.

[0046] The difference between this embodiment and embodiment 1 is that the slide rail 2 is a side longitudinal beam 202, and a middle longitudinal beam 203 is arranged between the opposite side longitudinal beams 202. A cross beam 204 connects the side longitudinal beams 202 and the middle longitudinal beams 203. Thus, the side longitudinal beams 202, the middle longitudinal beams 203 and the cross beams 204 together form a grid-shaped frame beam. The platform plate 4 is not only supported by the side longitudinal beams 202 on both sides, but also by the middle longitudinal beam 203 in the middle, so as to be suitable for scenarios with a large lateral span.

[0047] The side longitudinal beams 202, the middle longitudinal beams 203, and the transverse beams 204 are welded together to form an integral frame beam structure. Angle plates 205 are welded at the connection between the side longitudinal beams 202 and the middle longitudinal beams 203 to enhance the connection strength between the beams. The frame beam structure partially obstructs the opening of the slag pit 1, but it is suitable for scenarios with a large lateral span, so the obstructed area is small and does not affect normal construction.

[0048] The middle of both ends of the platform plate 4 are connected to the central traction device 602 via traction ropes 5. That is, each end is driven by a single central traction device 602. The form is relatively simple, but the central traction device 602 needs to have a large power.

[0049] Everything else is the same as in Example 1.

[0050] The foregoing basic examples and their further alternative examples can be freely combined to form multiple embodiments, all of which are embodiments that can be adopted and claimed in this application. In the scheme of this application, each alternative example can be arbitrarily combined with any other basic example and alternative example.

[0051] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this application should be included within the protection scope of this application.
