Description

Technical Field

[0001] The present invention belongs to the technical field of water conservancy projects, and particularly relates to a hand-electric dual-purpose opening and closing horizontal sliding gate. Background Art

[0002] The horizontal sliding gate is a common type of gate in water conservancy projects, and is mostly seen in ship locks with single or double-way water heads. Currently, the commonly used opening and closing methods are the following three forms: driven by a hydraulic hoist, pulled and driven by a winch-type hoist, and directly driven by a motor for the running wheels.

[0003] The existing horizontal sliding gate using the hydraulic hoist drive method is more suitable when the stroke of the horizontal sliding gate is relatively short. However, when the stroke of the horizontal sliding gate is very long, the hydraulic cylinder of the hydraulic hoist will be very long, the equipment occupies a large space, and the price is expensive; the method of using a winch to pull the horizontal sliding gate to open and close is relatively complicated, the installation is very troublesome, and the opening and closing accuracy of the gate is low. Therefore, the method of directly driving the running wheels by a motor is widely used. For the existing horizontal sliding flat gate, the motor reducer directly drives the running wheels. This method is simple and compact, but the running wheels are prone to slipping, resulting in a reduction in the safety and reliability of opening, closing, and closing the gate.

[0004] In order to prevent the leakage and jet water flow from causing the gate vibration or cavitation of the water stop seat on the gate body of the existing horizontal sliding gate, a gate water stop anti-leakage device is usually installed on the gate body. After the gate body is opened, the sediment in the water flow may enter the area where the gate water stop moves and deposit in this position. Since the gate water stop is made of rubber material and has a certain deformation ability, when the gate is closed, the deposited sediment may cause the deformation of the gate water stop, thereby reducing the anti-leakage effect of the device. Summary of the Invention

[0005] The purpose of the present invention is to solve the above problems. The present invention provides a hand-electric dual-purpose opening and closing horizontal sliding gate, which has the advantages of improving the safety and reliability of opening and closing the gate and the anti-leakage effect.

[0006] To achieve the above object, the present invention provides the following technical solution: A horizontal sliding door that can be opened and closed manually and electrically, comprising a driving device and a pier. The driving device includes a motor. The bottom end of the motor is drivingly connected to a first-stage reducer. Start the motor and make it rotate forward. At this time, the power of the motor is transmitted to the transmission gear through the first-stage reducer. The first-stage reducer drives the transmission gear to rotate by reducing speed. The left end of the first-stage reducer is drivingly connected to a transmission gear. The bottom end of the first-stage reducer is fixedly installed with a reducer seat. A second-stage reducer is provided at the right end of the first-stage reducer. Rotate the crank clockwise. The power generated when the crank rotates is transmitted to the transmission gear after being reduced by the second-stage reducer and the first-stage reducer. The right end of the second-stage reducer is drivingly connected to a crank. The left end of the second-stage reducer is drivingly connected to a semi-clutch. A locking screw is inserted into the top end of the semi-clutch. The semi-clutch provided between the second-stage reducer and the first-stage reducer is used to connect and disconnect the power source for manual operation through the locking screw. The bottom end of the reducer seat is installed on the gate bottom plate. A gate body is provided above the gate bottom plate. There are a rack and a leakage prevention component at the bottom end of the right side of the gate body. By the meshing of the transmission gear and the rack, the gate body installed on the left side of the rack can be driven to move backward, so that the gate body is in an open state. Travel wheels are fixedly installed on both the front and rear sides of the bottom end of the gate body. Travel tracks are fixedly installed on the top end of the gate bottom plate.

[0007] As a preferred technical solution of the present invention, the leakage prevention component includes a connecting plate. The connecting plate is fixedly installed on the right side of the bottom end of the gate body. A gate water stop is fixedly installed on the right side surface of the connecting plate. The top end of the gate water stop is fixedly connected to the connecting plate through a fixing bolt. Installation shafts are inserted into both the front and rear ends of the gate water stop. A push block is fixedly installed at the end of the push block extending out of the gate water stop. When the gate body moves back and forth, the gate body drives the gate water stop to move back and forth with the gate body through the connecting plate and the fixing bolt. When moving, it can drive the push block to scrape the deposited sediment within the area where the gate water stop moves.

[0008] As a preferred technical solution of the present invention, an anti-overturning wheel is fixedly installed at the bottom end of the front side surface of the gate body. The projection of the anti-overturning wheel in the vertical direction is located above the travel wheel. By setting the anti-overturning wheel, a lateral supporting force can be provided for the gate body to prevent the gate body from tipping over during movement, improving the safety of the device.

[0009] As a preferred technical solution of the present invention, the gate bottom plate is fixedly installed at the bottom end of the pier. The travel wheel is movably connected to the inner cavity of the travel track. The leakage prevention component is located below the rack. The gate bottom plate fixedly installed on the pier guides and positions the movement of the gate body respectively.

[0010] As a preferred technical solution of the present invention, the locking screw is in transmission connection with the primary speed reducer, and the crank is in a separable transmission connection with the transmission gear through a secondary speed reducer, a semi-clutch and a transmission gear. The transmission gear meshes with the rack, and in case of emergency, the gate body can be manually opened by the crank for opening and closing under the condition of no power supply.

[0011] As a preferred technical solution of the present invention, the push block is in the shape of a triangular pyramid, the bottom surface of the push block is on the same horizontal plane as the bottom end of the gate water stop, and the bottom surface of the push block is a plane. Since the push block is in the shape of a triangular pyramid and the left and right side surfaces are inclined surfaces, when the push block contacts the sediment and drives the sediment to move, the sediment can be pushed out of the area where the gate water stop moves, so as to reduce the sediment in the area where the gate water stop moves.

[0012] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0013] 1. By changing the way of directly driving the traveling wheel to rotate by using a motor speed reducer in the prior art, and driving the driving power to drive the transmission gear to rotate through the deceleration of the primary speed reducer, and driving the rack to rotate through the meshing of the transmission gear and the rack, thereby driving the gate body to move back and forth, the present invention avoids the situation of the traveling wheel slipping caused by directly driving the traveling wheel, thus improving the safety and reliability of the device when opening and closing.

[0014] 2. The present invention drives the gate water stop to move back and forth with the gate body. When moving, the push block can be driven to scrape the deposited sediment within the area where the gate water stop moves. Since the left and right side surfaces of the push block are inclined surfaces, when the push block contacts the sediment and drives the sediment to move, the sediment can be pushed out of the area where the gate water stop moves, so as to reduce the sediment in the area where the gate water stop moves, thereby avoiding the deformation of the gate water stop caused by sediment and improving the anti-leakage effect of the device.

Specific embodiments

[0023] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0024] Such as Figures 1 to 7As shown in the figure, the present invention provides a horizontal sliding door that can be opened and closed manually and electrically, including a driving device 100 and a pier 800. The driving device 100 includes a motor 101. The bottom end of the motor 101 is drivingly connected to a first-stage reducer 102. Start the motor 101 to make the motor 101 rotate forward. At this time, the power of the motor 101 is transmitted to the transmission gear 103 through the first-stage reducer 102. The first-stage reducer 102 drives the transmission gear 103 to rotate through speed reduction. The left end of the first-stage reducer 102 is drivingly connected to the transmission gear 103. The bottom end of the first-stage reducer 102 is fixedly installed with a reducer seat 104. A second-stage reducer 106 is provided at the right end of the first-stage reducer 102. Rotate the crank 105 clockwise. The power generated when the crank 105 rotates is transmitted to the transmission gear 103 after being reduced by the second-stage reducer 106 and the first-stage reducer 102. The right end of the second-stage reducer 106 is drivingly connected to the crank 105. The left end of the second-stage reducer 106 is drivingly connected to a semi-clutch 107. A locking screw 108 is inserted into the top end of the semi-clutch 107. The semi-clutch 107 provided between the second-stage reducer 106 and the first-stage reducer 102 is used to connect and disconnect the power source of the manual operation through the locking screw 108. The bottom end of the reducer seat 104 is installed on the gate bottom plate 700. Above the gate bottom plate 700, there is a gate body 300. At the bottom end of the right side of the gate body 300, there are a rack 200 and a leak-proof component 600. By the engagement of the transmission gear 103 and the rack 200, the gate body 300 installed on the left side of the rack 200 can be driven to move backward, so that the gate body 300 is in an open state. Travel wheels 400 are fixedly installed on both the front and rear sides of the bottom end of the gate body 300. Travel tracks 500 are fixedly installed on the top end of the gate bottom plate 700.

[0025] Among them, the leak-proof component 600 includes a connecting plate 601. The connecting plate 601 is fixedly installed on the right side of the bottom end of the gate body 300. A gate water stop 602 is fixedly installed on the right side surface of the connecting plate 601. The top end of the gate water stop 602 is fixedly connected to the connecting plate 601 through a fixing bolt 603. Installation shafts 605 are inserted into both the front and rear ends of the gate water stop 602. A push block 604 is fixedly installed at one end of the push block 604 extending out of the gate water stop 602. When the gate body 300 moves back and forth, the gate body 300 drives the gate water stop 602 to move back and forth along with the gate body 300 through the connecting plate 601 and the fixing bolt 603. When moving, it can drive the push block 604 to scrape the deposited sediment within the moving area of the gate water stop 602.

[0026] Among them, an anti-overturning wheel 900 is fixedly installed at the bottom end of the front side of the gate body 300. The projection of the anti-overturning wheel 900 in the vertical direction is located above the travel wheel 400. By setting the anti-overturning wheel 900, a lateral supporting force can be provided for the gate body 300 to prevent the gate body 300 from tipping over during movement, improving the safety of the device.

[0027] Among them, the sluice floor 700 is fixedly installed at the bottom end of the pier 800, the traveling wheels 400 are movably connected in the inner cavity of the traveling track 500, the anti-seepage component 600 is located below the rack 200, and the sluice floor 700 is fixedly installed on the pier 800 to respectively guide and position the movement of the gate body 300.

[0028] Among them, the locking screw 108 is in transmission connection with the first-stage reducer 102, and the crank 105 is in a separable transmission connection with the transmission gear 103 through the second-stage reducer 106, the half clutch 107 and the transmission gear 103. The transmission gear 103 meshes with the rack 200. In an emergency, the gate body 300 can be manually opened through the crank 105 for opening and closing under the condition of no power supply.

[0029] Among them, the push block 604 is in the shape of a triangular pyramid. The bottom surface of the push block 604 is on the same horizontal plane as the bottom end of the gate water stop 602. The bottom surface of the push block 604 is a plane. Since the push block 604 is in the shape of a triangular pyramid and the left and right side surfaces are inclined surfaces, when the push block 604 contacts the sediment and drives the sediment to move, the sediment can be pushed out of the moving area of the gate water stop 602, so as to reduce the sediment in the moving area of the gate water stop 602.

[0030] The working principle and usage process of the present invention:

[0031] During use, it is divided into two modes: electric control operation and manual operation;

[0032] For the opening of the electric control operation, first operate the half clutch 107 to disengage the second-stage reducer 106 from the first-stage reducer 102, and then use the locking screw 108 to lock the second-stage reducer 106 through the half clutch 107, so that the second-stage reducer 106 and the first-stage reducer 102 remain disengaged continuously. Then start the motor 101 to make the motor 101 rotate forward. At this time, the power of the motor 101 is transmitted to the transmission gear 103 through the first-stage reducer 102. The first-stage reducer 102 drives the transmission gear 103 to rotate through speed reduction. Through the meshing of the transmission gear 103 and the rack 200, the gate body 300 installed on the left side of the rack 200 can be driven to move backward, so that the gate body 300 is in an open state. On the contrary, the motor 101 rotates in reverse, thereby driving the gate body 300 to move forward, so that the gate body 300 is in a closed state;

[0033] For the manual operation to start, first operate the semi-clutch 107 to connect the secondary speed reducer 106 with the primary speed reducer 102. Then use the locking screw 108 to lock the secondary speed reducer 106 through the semi-clutch 107, so that the secondary speed reducer 106 and the primary speed reducer 102 remain continuously connected. Then rotate the crank 105 clockwise. The power generated during the rotation of the crank 105 is transmitted to the transmission gear 103 after being decelerated by the secondary speed reducer 106 and the primary speed reducer 102. Through the meshing of the transmission gear 103 with the rack 200, the gate body 300 can be driven to move backward, making the gate body 300 in the open state. Conversely, rotate the crank 105 counterclockwise, thereby driving the gate body 300 to move forward, making the gate body 300 in the closed state;

[0034] When the gate body 300 moves back and forth, the gate body 300 drives the gate water stop 602 to move back and forth through the connecting plate 601 and the fixing bolt 603. During the movement, the push block 604 can be driven to scrape the deposited sediment within the area where the gate water stop 602 moves. Since the left and right sides of the push block 604 are inclined surfaces, when the push block 604 contacts the sediment and drives the sediment to move, the sediment can be pushed out of the area where the gate water stop 602 moves, thereby reducing the sediment within the moving area of the gate water stop 602.
