Description
Technical Field
[0001] The utility model belongs to the technical field of water conservancy and hydropower engineering, and particularly relates to a labor-saving and space-saving gate locking device. Background Technique
[0002] The steel gate locking device for water conservancy and hydropower projects is to fix the gate at a specified elevation in the gate slot, and it is a safety fixing device for the gate in the open discharge state or during maintenance, which can avoid the hoist bearing the load for a long time.
[0003] At present, the common locking device types in water conservancy and hydropower projects include simply supported beam type locking, vertical flipping type locking, flipping claw type locking, walking beam type locking, etc. For large and extra-large hydraulic steel gates, their locking devices are heavy. The simply supported beam type locking is laborious to move, and the flipping claw type locking and electric walking beam type locking have high requirements for the installation of embedded parts and poor reliability. The existing vertical flipping locking device has a large rotation angle, a bulky cantilever structure, and needs to overcome gravity, making the operation difficult.
[0004] The patent document with the publication number of CN213867671U discloses a "semi-automatic gate locking device", which includes a foundation platform. The upper part of the foundation platform is rotatably connected to a locking structure through a support structure with a certain height. A handle is arranged on the locking structure. By applying force to the handle, the locking structure can be driven to rotate relative to the support structure to realize the locking or unlocking of the locking structure and the gate. A support column is arranged at the bottom of the locking structure near the gate end to support the locking structure to maintain lateral balance in the locked state. A counterweight is arranged at the top of the locking structure far from the gate end to adjust the center of gravity of the locking structure to move to the left. The end of the locking structure far from the gate has an inclined surface inclined towards the gate, and when the locking structure rotates until it is unlocked from the gate, this end does not contact the foundation platform. The locking structure can be fixed on the support structure through bolts and nuts for fixing when the locking structure is unlocked. A spring washer is arranged at the joint of the nut and the locking structure. The support structure and the locking structure are rotatably connected through a rotating support shaft, and a split pin is arranged on the rotating support shaft to ensure the axial positioning of the rotating support shaft. The support structure is fixedly connected to an embedded plate arranged on the top of the foundation platform. The locking structure is set as a box girder. The gate is set as a plane gate or an arc gate.
[0005] During the use of this application, when the gate needs to be lowered to block water, through manual intervention, the handle is used to drive the box girder to rotate to the unlocking position, and the box girder is fixed on the support frame with bolts, spring washers and nuts, so that the box girder is safely and reliably in the unlocked state, and the gate can move up and down freely to block water; after the gate is closed to block water, through manual intervention, the bolts, spring washers and nuts are removed, so that the box girder is in the state of waiting for automatic locking. When the gate needs to be locked, through manual intervention, the gate is lifted from the orifice, so that the gate locking plate is located above the box girder, and then the gate is lowered so that the gate locking plate is placed on the box girder to realize the automatic locking of the gate.
[0006] During the use of this application, it is necessary to rely on bolts and nuts to fix the box girder, and the operation is relatively cumbersome. Moreover, when the box girder is working, there is no limit to the rotation angle of the box girder, and mistakes are prone to occur during the operation, and there are also certain safety hazards. Utility Model Content
[0007] The purpose of the present utility model is to provide a gate locking device that saves labor and space. The gate is supported through the simple mechanical cooperation of the locking beam and the support seat, and the structure is stable. At the same time, the rotation angle of the locking beam is minimized through the cooperation of the flange plate and the support panel. It not only saves labor and is easy to operate, occupies a small space in the pier, but also has high safety.
[0008] The technical solution adopted by the present utility model is a gate locking device that saves labor and space, including two groups of symmetrically arranged gate locking units. The gate locking unit includes a pre-embedded base, a locking beam and a support seat. The pre-embedded base is fixed in the concrete on both sides of the gate slot. The bottom end of the locking beam is rotatably connected to the pre-embedded base, and the support seat is fixedly arranged on the side of the gate and can interfere with the locking beam to prevent the gate from descending.
[0009] Further, the pre-embedded base includes anchor bolts, a bottom plate and ear plates. The anchor bolts are embedded in the concrete on both sides of the gate slot. The bottom plate is fixedly installed at the top end of the anchor bolts through nuts. There are two ear plates and they are symmetrically and fixedly connected to both sides of the bottom plate. The bottom end of the locking beam is rotatably connected to the two ear plates.
[0010] Further, a hinge shaft is fixedly installed on the ear plate, and the bottom end of the locking beam is rotatably sleeved on the hinge shaft.
[0011] Further, a stop shaft plate is fixedly arranged on the outer side surface of the ear plate.
[0012] Further, a support panel is fixedly installed on the bottom plate, and a triangular flange plate is fixedly arranged at the bottom end of the locking beam. The flange plate can interfere with the support panel during the rotation of the locking beam, thereby restricting the rotation range of the locking beam.
[0013] Furthermore, pull rings are provided on both sides of the top end of the locking beam.
[0014] The beneficial effects of the present utility model are as follows:
[0015] 1. The present utility model supports the gate through the simple mechanical cooperation of the locking beam and the support base, with a stable structure. At the same time, the rotation angle of the locking beam is minimized through the cooperation of the flange plate and the support panel, which not only saves labor and is easy to operate, occupies a small space in the pier, but also has high safety.
[0016] 2. The labor-saving and space-saving gate locking device provided by the present utility model transfers the self-weight load of the plane gate to the bottom foundation through the support cooperation of the locking beam and the embedded base, which can ensure that the plane gate will not accidentally fall due to the fatigue failure of the locking beam caused by the disturbance of water flow and waves at the bottom of the plane gate.

[0023] In order to make the purpose, technical solutions and advantages of the present utility model clearer and more understandable, the technical solutions of the present utility model will be further described in detail below with reference to the accompanying drawings in the embodiments of the present utility model.
[0024] Refer to Figures 1 to 5, a labor-saving and space-saving gate locking device of the present utility model includes two groups of symmetrically arranged gate locking units. Each gate locking unit includes an embedded base 1, a locking beam 2, and a support seat 3. The embedded base 1 is fixed in the concrete on both sides of the gate slot of the gate 4. The bottom end of the locking beam 2 is rotatably connected to the embedded base 1. The support seat 3 is fixedly arranged on the side of the gate 4 and can interfere with the locking beam 2 to prevent the gate 4 from descending.
[0025] The two groups of gate locking units are symmetrically arranged, so the two locking beams 2 can cooperate with the support seats 3 on both sides of the gate 4 to support the gate 4. In the support state, the two locking beams 2 are in a V-shaped configuration. Correspondingly, when the locking beams 2 rotate outward to release the gate 4, the two locking beams 2 are in an inverted V-shaped configuration, allowing the gate 4 to close smoothly.
[0026] The locking beam 2 has an outer shape of a polygonal cantilever beam structure. Since the cantilever beam mainly bears the bending moment at the root, the root cross-section is large and the end cross-section can be reduced. The locking beam 2 has a small self-weight and the center of gravity is close to the root, making it labor-saving to rotate.
[0027] The embedded base 1 includes anchor bolts 1-7, a bottom plate 1-5, and ear plates 1-1. The anchor bolts 1-7 are embedded in the concrete on both sides of the gate slot of the gate 4. The bottom plate 1-5 is fixedly installed at the top of the anchor bolts 1-7 through nuts 1-6. There are two ear plates 1-1 which are symmetrically and fixedly connected to both sides of the bottom plate 1-5. The bottom end of the locking beam 2 is rotatably connected to the two ear plates 1-1. A hinge shaft 1-2 is fixedly installed on the ear plates 1-1. The bottom end of the locking beam 2 is rotatably sleeved on the hinge shaft 1-2. A stop shaft plate 1-3 is fixedly arranged on the outer side surface of the ear plates 1-1.
[0028] The stop shaft plate 1-3 can prevent the hinge shaft 1-2 from coming out.
[0029] Preferably, the locking beam 2 is connected to the hinge shaft 1-2 through a bushing, and the bushing is a self-lubricating bushing, which helps to reduce the rotational friction force.
[0030] A support panel 1-4 is fixedly installed on the bottom plate 1-5. A triangular flange plate 2-1 is fixedly arranged at the bottom end of the locking beam 2. The flange plate 2-1 can interfere with the support panel 1-4 during the rotation of the locking beam 2, thereby restricting the rotation range of the locking beam 2.
[0031] When the locking beam 2 rotates to a certain angle, the flange plate 2-1 will contact the support panel 1-4, thereby restricting the further rotation of the locking beam 2 in this direction and thus restricting the rotation angle of the locking beam 2.
[0032] Pull rings 2-3 are arranged on both sides of the top end of the locking beam 2. Workers can pull the locking beam 2 to rotate through the pull rings 2-3.
[0033] The content not described in detail in this specification belongs to the prior art well-known to those skilled in the art. It should also be noted that in this specification, relational terms such as first and second are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any actual relationship or order between these entities or operations. Moreover, the term "comprising", "including" or any other variant thereof is intended to cover non-exclusive inclusion, so that a process, method, article or device comprising a series of elements not only includes those elements, but also includes other elements not expressly listed, or also includes elements inherent in such process, method, article or device. Without further limitation, an element defined by the statement "comprising an..." does not exclude the existence of additional identical elements in the process, method, article or device comprising the element.
