Description

Technical Field

[0001] This utility model relates to the field of working well technology, and in particular to a working well opening protection device and hoisting equipment. Background Technology

[0002] In the field of underground engineering construction, working shafts play a crucial role as key construction nodes. They are not only passageways for construction equipment and personnel to enter the underground environment, but also the fundamental support for the stability and safety of the entire underground engineering structure. The design and construction of working shafts must comprehensively consider factors such as geological conditions, surrounding environment, project scale, and construction technology to ensure their load-bearing capacity, waterproofing performance, and construction safety. Through precise geological exploration and scientific structural design, working shafts can provide a stable and reliable working platform for subsequent underground operations, ensuring the smooth progress of construction.

[0003] During well operations, concrete pipe piles need to be hoisted into the well, a process that places extremely high demands on construction technology and safety measures. As a crucial load-bearing component in underground engineering, the hoisting accuracy and installation quality of concrete pipe piles directly affect the stability and durability of the entire project. During hoisting, specialized hoisting equipment, combined with precise measurement and positioning techniques, must be used to ensure the pipe piles are accurately placed in their designated positions. Simultaneously, to ensure operational safety, a detailed hoisting plan must be developed, on-site safety management strengthened, and professional training provided to personnel. This ensures that the hoisting of concrete pipe piles can be completed efficiently and safely in the complex and ever-changing underground environment, laying a solid foundation for subsequent underground engineering construction.

[0004] In the existing technology, when hoisting pipe piles in the working well, a temporary crane needs to be set up outside the working well. However, the stability of the temporary crane is not high, and there are no protective devices around the working well. When hoisting the pipe piles, the pipe piles are prone to shaking, which may affect the surrounding objects and environment. Secondly, if no protective devices are set up, the operators are at risk of falling into the working well, which is not safe. Utility Model Content

[0005] The purpose of this utility model is to provide a working well opening protection device and hoisting equipment to solve the above-mentioned shortcomings in the prior art.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a working well opening protection device, comprising four support columns and four arc-shaped plates.

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0025] Reference Figure 1-5A protective device for the opening of a working well 101 includes four support columns 2 and four arc-shaped plates 7. The four support columns 2 are fixedly installed around the working well 101. Two of the arc-shaped plates 7 are fixedly installed between two of the support columns 2, and the other two arc-shaped plates 7 are fixedly installed between the other two support columns 2. Multiple railings 8 are fixedly installed between the two sets of arc-shaped plates 7. The arc-shaped plates 7 and railings 8 around the working well 101 can isolate and protect the working well 101. The anti-collision components 9 prevent the concrete pipe piles from swaying and colliding during hoisting, thus avoiding damage to the railings 8. Furthermore, the railings 8 and anti-collision components 9 can protect personnel outside the working well 101 and reduce the risk of accidents.

[0026] As a preferred technical solution in this embodiment, the anti-collision component 9 includes an elastic plate 901, with plug-in plates 10 fixedly connected to both ends of the elastic plate 901. The plug-in plates 10 are inserted between two support columns 2 and the railings 8 at both ends. Multiple expansion strips 903 are fixedly installed on the elastic plate 901, and the multiple expansion strips 903 are respectively inserted between multiple railings 8. The elastic plate 901 of the anti-collision component 9 is made of rubber elastic material. During the installation process, there is no need for cumbersome bolt fixing. Moreover, the anti-collision component 9 only needs to be temporarily installed when hoisting concrete piles. It does not need to be added during non-installation periods. By bending the elastic plate 901, the multiple expansion strips 903 are snapped between multiple railings 8. The bent elastic plate 901 can fit tightly against the railings 8 and will not fall off, thereby realizing the simple installation of the anti-collision component 9.

[0027] As a preferred technical solution of this embodiment, the elastic plate 901 has a groove 902 on one side where the expansion strip 903 is provided. The groove 902 is provided between multiple expansion strips 903 and is adapted to multiple railings 8. The groove 902 can engage multiple railings 8, so that the elastic plate 901 can be engaged not only by the expansion strip 903, but also by the groove 902 to increase its fixed stability.

[0028] As a preferred technical solution of this embodiment, a reinforcing strip 904 and a reinforcing rib 905 are provided on the side of the elastic plate 901 away from the expansion strip 903. A plurality of reinforcing strips 904 are provided at corresponding positions of the groove 902, and a plurality of reinforcing ribs 905 are provided between the plurality of reinforcing strips 904. Since the opening of the groove 902 will make the elastic plate 901 thinner, a reinforcing strip 904 is provided on the opposite side of the groove 902. The plurality of reinforcing strips 904 are connected by arc-shaped reinforcing ribs 905, which can increase the thickness of the elastic plate 901 and increase the impact resistance and protection performance of the elastic plate 901.

[0029] As a preferred technical solution of this embodiment, a protective door 13 is provided between the two supporting columns 2, and a sealing plate 11 is fixedly installed between the other two supporting columns 2. The bottom end of the sealing plate 11 is provided with a through groove 12. The protective door 13 enables personnel to go down into and out of the well, and leaves a certain space to facilitate the downward hoisting of concrete pipe piles. The groove 902 facilitates wiring from the outside to the inside, which is convenient for underground work.

[0030] A hoisting device includes a protective device for the opening of a working well 101, a rain shelter 3 fixedly installed on the top of multiple support columns 2, and a support beam 4 fixedly installed at the bottom of the rain shelter 3. Both ends of the support beam 4 are fixedly connected to the support columns 2, and an I-beam rail 5 is fixedly installed at the bottom of the support beam 4. An electric hoist 6 is mounted on the I-beam rail 5. The length of the I-beam rail 5 is greater than the diameter of the working well 101. The rain shelter 3 provides rain protection for the working well 101. The electric hoist 6 is existing technology; its function is to move along the I-beam rail 5 to a target position to lift and lower workpieces. Therefore, it is not described in detail. The electric hoist 6 can move to the outside of the working well 101 via the I-beam rail 5 to lift and lower concrete piles that need to be placed into the well. Compared to traditional temporary hoists, this device offers higher flexibility, stability, and safety.

[0031] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
