Description

Technical Field

[0001] This invention belongs to the field of gate installation technology, and relates to a gate installation in a narrow space, and more particularly to a gate installation method in a narrow space. Background Technology

[0002] A sluice gate is a device used to control the flow of water, air, or other substances. It can be used in water conservancy projects, sewage treatment, power plants, and other places to regulate water level, flow rate, or prevent backflow. There are many types of sluice gates, such as gate plates, gate valves, and gate openings. Different types of sluice gates are suitable for different scenarios and needs. Sluice gate installation is an important task in water conservancy projects, sewage treatment, and channel management.

[0003] A search revealed a Chinese patent document disclosing a method for gate hoisting in confined working spaces [Application No.: CN201910605597.5; Publication No.: CN110304588B]. For gate installation in confined spaces, the upper cavity of the gate is used as a space for rotation. The first and second gate sections are hoisted using the short side. After rotation in the upper cavity, they are placed upstream or downstream of the gate slot, reserving installation space for the gate slot. The third section is then hoisted using the short side, rotated in the upper cavity, and lowered into the gate slot. The second and first sections are then hoisted sequentially and placed into the gate slot.

[0004] The segmental gate assembly method disclosed in this patent can make full use of the narrow space above the gate slot and improve work efficiency. However, the transport of the gate in the narrow space is also difficult. In particular, the gate's entry position in the slot is narrow during the transport of the segmented gate, which may result in insufficient transport width. Moreover, the position of the gate needs to be adjusted after transport, which requires rotating the gate. However, this is not convenient to operate in a narrow space. Therefore, the above problems need to be solved. Summary of the Invention

[0005] The purpose of this invention is to address the aforementioned problems in existing technologies by proposing a method for installing gates in narrow spaces. The technical problem this invention aims to solve is: how to more conveniently and stably install gates in narrow spaces.

[0006] The objective of this invention can be achieved through the following technical solutions:

[0007] A method for installing a gate in a narrow space includes an electric vehicle, a gate, a birdcage, and a complete installation kit.

[0008] S1: A water collection pit is provided below the birdcage, and drainage ditches are provided at both ends of the bottom of the water collection pit;

[0009] S2: The gate is divided into 3 sections, which are connected by bolts. The installation method is from top to bottom, using an inverted installation method. The installation sequence is the top gate leaf, the middle gate leaf, and the bottom gate leaf. The specific process of gate installation is as follows: transport the top gate leaf → rotate the top gate leaf into the slot → lift the top gate leaf → transport the middle gate leaf → rotate the middle gate leaf into the slot → bolt the top and middle gate leaves together → rotate the bottom gate leaf into the slot → bolt the whole gate together → put the whole gate in place.

[0010] S3: The battery-powered vehicle is located at the bottom of the gate and transports the gate horizontally. The gate is transported to the installation site by the battery-powered vehicle via underground road transport. Since the installation site does not have the conditions for the gate to be turned over and rotated, the gate is transported by turning it over and fixing it during installation.

[0011] S4: The installation equipment consists of two sets, which are respectively located at the bottom ends of the gate. There is no hoisting space above the birdcage. The gate is transported from the sump to the bottom of the pool and hoisted over a short distance using a 30t bridge crane above the birdcage.

[0012] Preferably, the top of the electric vehicle has a circular groove, a top plate is rotatably connected to the top of the electric vehicle, a turntable is fixedly connected to the bottom of the top plate, the turntable is rotatably connected to the inside of the circular groove, the gate is placed on the top of the top plate, four support frames are fixedly connected to the top of the top plate, the four support frames are respectively arranged on both sides of the gate surface, a fixed frame is fixedly connected to the bottom of the electric vehicle, a rotating shaft is vertically fixedly connected to the center of the bottom of the turntable, the rotating shaft is rotatably fitted inside the electric vehicle, the bottom end of the rotating shaft is rotatably connected to the top of the fixed frame, a worm gear is fitted on the surface of the rotating shaft, a worm is rotatably connected inside the electric vehicle, the worm is horizontally arranged, the two ends of the worm are respectively rotatably fitted on opposite sides inside the fixed frame, the worm cooperates with the worm wheel, a motor is installed on the surface of the fixed frame, and the output end of the motor is fixedly connected to one end of the worm.

[0013] Furthermore, both ends of the top of the electric vehicle are vertically provided with lifting slots, and two limiting slots are vertically provided on opposite sides of the surfaces of the two lifting slots. Lifting columns are vertically slidably connected inside the two lifting slots. Limiting blocks are fixedly connected on both sides of the bottom of the two lifting columns. Multiple limiting blocks are slidably connected inside multiple limiting slots. Two first hydraulic telescopic cylinders are vertically fixedly connected inside the two lifting slots. The top of each pair of first hydraulic telescopic cylinders is fixedly connected to the top of each lifting column.

[0014] Preferably, the gate entry process is as follows: After the gate is transported to the drainage ditch by a battery-powered vehicle, the first hydraulic telescopic cylinder at the bottom of the two lifting columns is driven to slide the two lifting columns upward into the lifting ditch, thereby releasing the restriction on both ends of the bottom of the gate. Then, while the battery-powered vehicle is transporting the gate, the drive motor drives the worm gear to rotate. With the cooperation of the worm wheel, the rotating shaft and turntable will rotate, so that the top plate and the gate can rotate at the same time. Thus, the gate can rotate while being transported. Through the above two actions, the gate drill moves forward and can pass through the drainage ditch more stably.

[0015] Furthermore, a tank is installed at the bottom of the installation equipment, a rotary table is installed on the top of the tank, an extension rod is vertically fixedly connected to the top of the rotary table, a guide frame is fixedly connected to the surface of the extension rod, a second hydraulic telescopic rod is vertically fixedly connected to the top of the extension rod, and a connecting flange is installed on the top of the second hydraulic telescopic rod.

[0016] Preferably, the installation equipment is installed at both ends of the gate, and the second hydraulic telescopic rod of the installation equipment is raised to support the gate together with the rotating travel device of the top plate. Then, the gate is rotated and moved into the slot by the rotation of the top plate and the combined action of the tank and the battery vehicle.

[0017] Compared with the prior art, the narrow space gate installation method of the present invention has the following advantages:

[0018] 1. In this invention, during the installation of the gate, the structure on the top of the battery vehicle facilitates the rotation of the gate during transportation, thereby making it easier to transport the gate in narrow spaces and improving the convenience of gate transportation and installation.

[0019] 2. In this invention, during use, the two lifting columns can drive the first hydraulic telescopic cylinder to slide the two lifting columns upward, so that the two lifting columns can contact the bottom ends of the gate, thereby restricting the bottom ends of the gate and making the gate conveying process more stable.

Detailed Implementation

[0027] The following are specific embodiments of the present invention, which are described in conjunction with the accompanying drawings. However, the present invention is not limited to these embodiments.

[0028] like Figures 1-6 As shown, a method for installing a gate in a narrow space includes an electric vehicle 1, a gate 4, a birdcage 5, and a complete installation kit 6.

[0029] S1: A water collection pit 502 is provided below the birdcage 5, and drainage ditches 501 are provided at both ends of the bottom of the water collection pit 502;

[0030] S2: The gate is divided into 3 sections, which are connected by bolts. The installation method is from top to bottom, using an inverted installation method. The installation sequence is the top gate leaf, the middle gate leaf, and the bottom gate leaf. The specific process of gate installation is as follows: transport the top gate leaf → rotate the top gate leaf into the slot → lift the top gate leaf → transport the middle gate leaf → rotate the middle gate leaf into the slot → bolt the top and middle gate leaves together → rotate the bottom gate leaf into the slot → bolt the whole gate together → put the whole gate in place.

[0031] S3: The battery vehicle 1 is set at the bottom of the gate 4 to transport the gate 4 in a horizontal state. The gate is transported to the installation site by the battery vehicle 1. The transportation method is underground road transportation by battery vehicle. The installation site does not have the conditions for the gate to be turned over and rotated. The transportation is carried out by installation, turning over and fixing.

[0032] S4: There are two sets of installation equipment 6. The two sets of installation equipment 6 are respectively set at the bottom ends of the gate 4. There is no hoisting space above the birdcage 5. The gate 4 is transported from the sump 502 to the bottom of the pool and hoisted over a short distance using the 30t bridge crane above the birdcage 5.

[0033] The structure on the top of the battery vehicle 1 allows the gate 4 to be rotated during transport, making it easier to transport the gate 4 in narrow spaces and improving the convenience of transporting and installing the gate 4.

[0034] like Figure 2 , Figure 3 and Figure 4 As shown, the top of the electric vehicle 1 has a circular groove 101. A top plate 2 is rotatably connected to the top of the electric vehicle 1. A turntable 202 is fixedly connected to the bottom of the top plate 2. The turntable 202 is rotatably connected inside the circular groove 101. A gate 4 is placed on the top of the top plate 2. Four support frames 201 are fixedly connected to the top of the top plate 2. The four support frames 201 are respectively arranged on both sides of the surface of the gate 4. A fixed frame 102 is fixedly connected to the bottom of the electric vehicle 1. A rotating shaft 203 is vertically fixedly connected to the center of the bottom of the turntable 202. The rotating shaft 203 is rotatably fitted inside the electric vehicle 1. The bottom end of shaft 203 is rotatably connected to the top of fixed frame 102. A worm gear 204 is sleeved on the surface of shaft 203. A worm 205 is rotatably connected inside the electric vehicle 1. The worm 205 is horizontally arranged, and its two ends are respectively rotatably sleeved on opposite sides inside the fixed frame 102. The worm 205 cooperates with the worm gear 204. A motor 206 is mounted on the surface of fixed frame 102. The output end of motor 206 is fixedly connected to one end of worm 205. Lifting slots 103 are vertically opened at both ends of the top of the electric vehicle 1. The surfaces of the two lifting slots 103 are vertically opened on opposite sides. There are two limiting grooves 104, and two lifting grooves 103 are vertically slidably connected to lifting columns 3. Limiting blocks 301 are fixedly connected to both sides of the bottom of each lifting column 3. Multiple limiting blocks 301 are slidably connected to multiple limiting grooves 104. Two first hydraulic telescopic cylinders 302 are vertically fixedly connected to the inside of each lifting groove 103. The tops of each pair of first hydraulic telescopic cylinders 302 are fixedly connected to the top of each lifting column 3. The gate 4 is inserted into the groove as follows: After the gate 4 is transported to the drainage ditch 501 by the battery-powered vehicle 1, the two lifting columns are driven... The first hydraulic telescopic cylinder 302 at the bottom of column 3 causes the two lifting columns 3 to slide upward into the lifting groove 103, thereby releasing the restriction on both ends of the bottom of the gate 4. Then, while the battery vehicle 1 is transporting the gate, the drive motor 206 drives the worm gear 205 to rotate. With the cooperation of the worm wheel 204, the rotating shaft 203 and the turntable 202 will rotate, so that the top plate 2 and the gate 4 can rotate at the same time. Thus, the gate 4 can rotate while being transported. Through the above two actions, the gate 4 can be moved forward by drilling, so that it can pass through the inside of the drainage ditch 501 more stably.

[0035] like Figure 6 As shown, the bottom of the installation equipment 6 is equipped with a tank 606, and the top of the tank 606 is equipped with a rotary turntable 602. An extension rod 601 is vertically fixed to the top of the rotary turntable 602, and a guide frame 603 is fixedly connected to the surface of the extension rod 601. A second hydraulic telescopic rod 604 is vertically fixed to the top of the extension rod 601, and a connecting flange 605 is installed on the top of the second hydraulic telescopic rod 604. The installation equipment 6 is installed at both ends of the gate 4. At the same time, the second hydraulic telescopic rod 604 of the installation equipment 6 is lifted so that it and the rotating walking device of the top plate 2 support the gate 4. Then, the gate 4 rotates and moves into the slot by the rotation of the top plate 2, the combined action of the tank 606 and the battery vehicle 1.

[0036] The working principle of this invention is as follows: In actual use, the two lifting columns 3 drive the first hydraulic telescopic cylinder 302 to slide the two lifting columns 3 upwards, allowing them to contact the bottom ends of the gate 4. This restricts the bottom ends of the gate 4, making the transport of the gate 4 more stable. Subsequently, during the transport of the gate, the first hydraulic telescopic cylinder 302 at the bottom of the two lifting columns 3 needs to be controlled to slide the two lifting columns 3 upwards into the lifting groove 103, thus releasing the restriction on the bottom ends of the gate 4. Then, while the battery-powered vehicle 1 is transporting the gate, the drive motor 206 drives the worm gear 205 to rotate. With the cooperation of the worm gear 204, the rotating shaft 203 and the turntable 202 will rotate, which will cause the top plate 2 and the gate 4 to rotate simultaneously. Thus, the gate 4 can rotate while being transported. Through the above two actions, the gate 4 can move forward and pass through the drainage ditch 501 more stably. Then, the installation equipment 6 is installed at both ends of the gate 4. At the same time, the second hydraulic telescopic rod 604 of the installation equipment 6 is lifted so that it and the rotating walking device of the top plate 2 can support the gate 4. Then, the gate 4 rotates and moves into the ditch by the rotation of the top plate 2, the combined action of the tank 606 and the battery car 1.

[0037] In summary, in this invention, the structural design on the top of the battery vehicle 1 facilitates the rotation of the gate 4 during transport, thereby making it easier to transport the gate 4 in narrow spaces and improving the convenience of transporting and installing the gate 4.

[0038] The above description is only a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
