Description

Technical Field

[0001] This utility model relates to the field of elevator construction technology, specifically to a water pumping device for convenient elevator construction. Background Technology

[0002] Elevator construction water pumps are small water pumps specifically designed for elevator construction scenarios. During elevator shaft construction, water can easily accumulate in the shaft due to groundwater seepage, rainwater accumulation, or residual construction water. This water pump can quickly pump out the accumulated water and discharge it to a designated location, ensuring a dry construction environment and preventing water accumulation from damaging elevator equipment installation and electrical wiring.

[0003] For example, Chinese Patent Application No. 202220455670.2 discloses a vertical pipeline water pump, including a pump body. The outer wall of the pump body is fixed with a handle and a soundproof cover through an adjustment mechanism. The adjustment mechanism includes a lifting frame, a connecting shaft, a positioning plate, a lead screw, a positioning shaft, a slider, a slide groove, and a support plate. The positioning plate is installed on the front surface of the pump body, and the front surface of the positioning plate has a slide groove. When the pump body needs to be moved, the operator can hold the control panel and rotate it. With the cooperation of the lifting frame, connecting shaft, positioning plate, lead screw, positioning shaft, slider, slide groove, and support plate inside the adjustment mechanism, the handle can be moved down to a suitable position. This makes it convenient for the operator to hold the handle and move the pump body. During the downward extension of the lifting frame, the soundproof cover completely covers the pump body, thereby blocking and absorbing the noise generated by the pump body and preventing the noise from spreading to the outside.

[0004] When using water pumping equipment during elevator construction, the pump is typically placed inside the elevator shaft for pumping operations. For ease of operation, two methods are generally used: one is to directly lower a vertical pump into the elevator shaft; the other is to hoist the pump down the shaft using ropes. However, during the pumping process, foreign objects may be present at the bottom of the elevator shaft, causing the pump to tip over upon contact. If the pump tipps over, it may compress or pull on the adjacent water pipes at the bottom, potentially leading to pipe detachment or leaks.

[0005] Therefore, it is necessary to redesign and modify the pumping device used for elevator construction to effectively prevent the water pipes from falling off or being damaged. Utility Model Content

[0006] To address the problems mentioned in the background art, the purpose of this utility model is to provide a water pumping device that is easy to use for elevator construction, and solves the problem of water pipes easily falling off or being damaged.

[0008] As a preferred embodiment of this utility model, the fixing mechanism includes a support plate fixedly connected to the outside of the extension block. A screw is movably connected to the inner wall of the rear support plate via a bearing. The threads on the upper and lower sides of the outer surface of the screw are opposite. Lifting plates are threadedly connected to the upper and lower sides of the outer surface of the screw. A clamping plate is fixedly connected to the outer side of the lifting plate. The clamping plate is used to fix the position of the clamping frame and prevent it from moving. A limit rod is fixedly connected to the inner wall of the front support plate. The surface of the limit rod is slidably connected to the inner wall of the lifting plate.

[0009] As a preferred embodiment of this invention, a knob is fixedly connected to the upper end of the screw, and the knob is used to facilitate the rotation of the screw by the fingers.

[0010] As a preferred embodiment of this invention, handles are fixedly connected to the front and rear sides of the protective frame, and the handles are used to facilitate the installation and disassembly of the protective frame.

[0011] As a preferred embodiment of this invention, the outer side of the support plate is provided with rounded corners, which are used to prevent sharp edges from scratching the operator.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] like Figures 1 to 4 As shown, this utility model provides a water pumping device for elevator construction, including a water pump 1, an outlet 2 installed on the left side of the water pump 1, an outlet pipe 3 installed on the upper side of the outlet 2, a protective mechanism on the left side of the outlet pipe 3, the protective mechanism including a fixing block 4 fixedly connected to the upper and lower sides of the left side of the water pump 1, a clamp 5 fixedly connected to the left side of the fixing block 4 for fixing the position of the outlet pipe 3, extension blocks 6 fixedly connected to the front and rear sides of the fixing block 4, a slot 7 opened on the left side of the extension block 6, a protective frame 8 slidably connected inside the slot 7, four clip frames 9 fixedly connected to the surface of the protective frame 8, and a fixing mechanism on the left side of the water pump 1.

[0023] refer to Figure 4The fixing mechanism includes a support plate 10 fixedly connected to the outside of the extension block 6. The inner wall of the rear support plate 10 is movably connected to a screw 11 via a bearing. The threads on the upper and lower sides of the outer surface of the screw 11 are opposite. The upper and lower sides of the outer surface of the screw 11 are threadedly connected to a lifting plate 12. A clamping plate 13 is fixedly connected to the outside of the lifting plate 12. The clamping plate 13 is used to fix the position of the clamping frame 9 and prevent it from moving. A limit rod 14 is fixedly connected to the inner wall of the front support plate 10. The surface of the limit rod 14 is slidably connected to the inner wall of the lifting plate 12.

[0024] As a technical optimization of this utility model, by setting a fixing mechanism, the position of the card frame 9 on the protective frame 8 can be firmly fixed to prevent the protective frame 8 from moving and ensure the stable protection of the water outlet pipe 3 by the protective frame 8; the limiting rod 14 on the front support plate 10 can ensure that the lifting plate 12 can only move up and down, so that the card plate 13 can accurately fix the card frame 9, thereby improving the accuracy and reliability of fixing.

[0025] refer to Figure 4 A knob 15 is fixedly connected to the upper end of the screw 11. The knob 15 is used to facilitate the rotation of the screw 11 by the fingers.

[0026] As a technical optimization of this utility model, by setting the knob 15, it is convenient for operators to turn the screw 11 with their fingers without the need for other tools, making the installation and disassembly of the protective frame 8 more convenient and labor-saving, and improving construction efficiency.

[0027] refer to Figure 2 Handles 16 are fixedly connected to the front and rear sides of the protective frame 8. The handles 16 are used to facilitate the installation and disassembly of the protective frame 8.

[0028] As a technical optimization of this utility model, by setting a handle 16, a point of leverage is provided for the operator, making it easier to grip and operate when installing and disassembling the protective frame 8, further improving the convenience of installation and disassembly and reducing the difficulty of operation.

[0029] refer to Figure 4 The outer side of the support plate 10 is provided with rounded corners 17, which are used to prevent sharp edges from scratching the operator.

[0030] As a technical optimization of this utility model, by setting the rounded corner 17, the sharp edges of the support plate 10 can be prevented from scratching the operators, thereby improving the safety of equipment use, reflecting humanized design, and reducing the risk of personnel injury during construction.

[0031] refer to Figure 2 The surface of the protective frame 8 is provided with an angle 18, which makes it easier for the protective frame 8 to be inserted into the slot 7.

[0032] As a technical optimization of this utility model, by setting the bevel angle 18, when the protective frame 8 is inserted into the slot 7, the bevel angle 18 can play a guiding role, making it easier and smoother for the protective frame 8 to be inserted into the slot 7, reducing jamming and resistance during the installation process, and improving the efficiency and accuracy of installation.

[0033] The working principle and usage process of this utility model are as follows: In use, the water outlet pipe 3 is initially fixed to the left outlet 2 of the water pump 1 using the clamp 5. The protective frame 8 is then inserted into the slot 7 on the extension block 6, at which point the protective frame 8 conceals the clamp 5 and the water outlet pipe 3 within it. Rotating the screw 11 on the rear support plate 10 of the fixing mechanism causes the upper and lower lifting plates 12 to move due to the opposite threads on the upper and lower sides of the screw 11, which are respectively threaded to the lifting plates 12. Under the limiting action of the limiting rod 14 on the lifting plates 12, the rotation of the screw 11 moves the upper and lower lifting plates 12, causing the lifting plates 12 to move and the clamping plate 13 to move, clamping the clamping plate 13 to the left side of the clamping frame 9, thus fixing the protective frame 8 and protecting the water outlet pipe 3. For disassembly, the screw 11 is rotated in the opposite direction to disengage the clamping plate 13 from the clamping frame 9, and it can be pulled out using the handle 16 on the protective frame 8. This design avoids the easy crushing of the water outlet pipe 3 by the elevator construction water pump 1, resulting in its ease of use.

[0034] In summary, when this utility model is used, the water outlet pipe 3 of the water pump 1 can be fixed and protected under the action of the protective mechanism and the fixing mechanism, which avoids the water pump 1 used for elevator construction from being easily squeezed and causing the water outlet pipe 3 to fall off or be damaged, thus giving it the advantage of being easy to use.
