Description

Technical Field

[0001] This utility model relates to the field of gate control technology, specifically an integrated opening and closing device. Background Technology

[0002] Screw-type gate hoists are widely used equipment in water conservancy projects. Their working principle is based on the mechanical cooperation of screw and nut to convert rotational motion into linear motion, thereby achieving precise control of the gate. During the use of the gate, it is necessary to limit the raising and lowering of the gate.

[0003] Existing screw-type gate hoists require maintenance personnel to add lubricating oil to the screw regularly. Each time oil is added, it takes a considerable amount of time to move the screw up and down to distribute the lubricating oil evenly, making maintenance inconvenient. Therefore, an integrated gate hoisting device has been proposed to solve the above problems. Utility Model Content

[0004] In view of the shortcomings of the existing technology, this utility model provides an integrated opening and closing device, which has the advantages of easy maintenance and solves the problem that the existing opening and closing devices are relatively inconvenient to maintain.

[0005] To achieve the above objectives, this utility model provides the following technical solution: an integrated opening and closing device, comprising a base plate and an opening and closing machine, wherein the opening and closing machine is mounted on the base plate, a screw is threaded onto the opening and closing machine, the screw passes through and extends below the base plate, a protective shell is provided on the base plate, an integrated gate position limit switch is provided on the top of the opening and closing machine, an mounting plate is provided on the opening and closing machine, the mounting plate is sleeved on the outside of the screw, an oil storage tank is provided on the mounting plate, and a tank cover is provided on the oil storage tank.

[0006] Furthermore, an installation assembly is provided below the base plate. The installation assembly includes a channel steel, a clamping plate, mounting holes, a threaded rod, and nuts. The channel steel is symmetrically arranged below the base plate, and the clamping plate is arranged below the channel steel. Multiple mounting holes are symmetrically arranged on the clamping plate and the channel steel. The two ends of the threaded rod pass through the mounting holes on the upper and lower sides, respectively, and nuts are threaded onto both ends of the threaded rod.

[0007] Furthermore, a protective sleeve is provided on the top of the protective shell and above the screw, and an insect-proof sleeve with one end in contact with the hoist is provided on the top of the bottom plate, which is sleeved on the outside of the screw.

[0008] Furthermore, a rocker arm hole is provided on the left side of the protective shell, and a cover is movably installed at the rocker arm hole.

[0009] Furthermore, a number of gaskets are symmetrically arranged between the base plate and the gate hoist, and the gate hoist is provided with a bolt that passes through the gasket and extends into the base plate.

[0010] Furthermore, weighing sensors are symmetrically arranged between the base plate and the gate hoist, and the gate hoist is provided with a bolt that passes through a gasket and extends into the base plate.

[0011] Furthermore, a normally closed switch is provided on the base plate and on the left side of the gate hoist.

[0012] Compared with the prior art, the technical solution of this application has the following beneficial effects: 1. This integrated opening and closing device, through the oil reservoir, allows for convenient and quick oiling and maintenance of the screw during screw maintenance. Grease is added into the oil reservoir, and the reservoir cover is closed. As the screw moves up and down, the grease inside the reservoir cover adheres to the screw. This achieves the purpose of easy maintenance.

[0013] 2. This integrated opening and closing device, through its set installation components, can be conveniently and quickly installed on gates under different working conditions, thus improving the practicality of the device.

[0014] 3. This integrated opening and closing device, through the insect-proof sleeve, can effectively prevent insects from entering the protective shell and avoid insects attaching to electronic components, thus preventing damage to the electronic components.

[0015] 4. This integrated opening and closing device integrates the opening and closing machine with the gate position limit switch inside the protective housing, making the opening, closing and limiting of the gate a single unit. This not only increases the aesthetics of the device but also provides good protection for the internal components and increases the service life of the device. Attached Figure Description

[0020] Specifically, during use, the mounting plate 6 is fixed on the hoist 3, the cylinder cover 8 is removed, grease is added into the oil reservoir 7, the cylinder cover 8 is closed, and as the screw 2 moves up and down, the grease in the cylinder cover 8 can adhere to the screw 2. In this way, oiling and maintaining the screw 2 is very convenient and quick.

[0021] It should be noted that the mounting plate 6 has holes that match the mounting holes on the top cover of the hoist 3. Therefore, there is no need to drill additional holes on the top cover of the hoist 3. Simply remove the fixing bolts on the top cover of the hoist 3, align the holes on the mounting plate 6 with the mounting holes on the top cover of the hoist 3, and tighten the fixing bolts to complete the installation of the mounting plate 6 without damage.

[0022] In this embodiment, an installation assembly 13 is provided below the base plate 1. The installation assembly 13 includes a channel steel 131, a clamping plate 132, mounting holes 133, a threaded rod 134, and a nut 135. The channel steel 131 is symmetrically arranged below the base plate 1, and the clamping plate 132 is arranged below the channel steel 131. Multiple mounting holes 133 are symmetrically arranged on the clamping plate 132 and the channel steel 131. The two ends of the threaded rod 134 pass through the mounting holes 133 on the upper and lower sides, respectively, and the two ends of the threaded rod 134 are threaded with nuts 135.

[0023] Specifically, the channel steel 131 is placed on top of the gate frame, and the screw 2 is positioned between the two channel steels 131. One end of the threaded rod 134 is fixed to the clamping plate 132. The clamping plate 132 is moved to fit tightly against the inner top wall of the gate frame, and the threaded rod 134 is passed through the mounting hole 133 on the channel steel 131. The nut 135 is tightened to fix the base plate 1 to the gate frame. In addition, the multiple mounting holes 133 can be used to adjust the spacing of the threaded rods 134 according to the site conditions to meet different gate installation requirements.

[0024] In this embodiment, a protective sleeve 9 is provided on the top of the protective shell 4 and above the screw 2, and an insect-proof sleeve 10 with one end in contact with the hoist 3 is provided on the top of the bottom plate 1, which is fitted onto the outside of the screw 2.

[0031] It should be noted that the normally closed switch 14 is electrically connected to the gate hoist 3.

[0032] Specifically, when the rocker arm is not inserted into the gate hoist 3 for manual operation, the circuit of the gate hoist 3 is open, and the gate hoist 3 can be remotely controlled; after the rocker arm is inserted, the circuit of the gate hoist 3 is disconnected after the rocker arm contacts the normally closed switch 14, so as to avoid injury to personnel caused by remote operation of the motor during manual operation.
