Description

Technical Field

[0001] The utility model belongs to the technical field of ship lifts, and in particular relates to a hydraulic bidirectional tightening ship lift ship compartment docking and locking device. Background Art

[0002] When the ship carriage of the fully balanced vertical ship lift is docked with the upstream and downstream waters, it is generally necessary to lock the ship carriage on the tower column through a docking locking device to prevent the ship carriage from vertically displacing during the docking period. In engineering, a docking locking device that relies on static friction for locking is often used. This docking locking device is generally divided into four groups and symmetrically arranged on both sides of the ship carriage. Each group of locking devices has a locking frame. The locking frame is provided with transverse and longitudinal guide wheels, which are connected to the ship carriage through supporting cylinders and pressed into the vertical groove on the tower column by hydraulic springs. When not locked, the entire device can move up and down in the tower column groove with the ship carriage. When docking and locking are performed, the tightening cylinders on both sides of the locking frame are pushed out, and the friction plates with high friction coefficient on the end faces of the cylinders are tightened on the friction surfaces of the track embedded parts. The static friction generated can realize the vertical locking of the ship carriage.

[0003] When docking and locking are performed, the tensioning cylinders on both sides of the locking frame are pushed out, and the friction plates with high friction coefficients on the end faces of the cylinders are tightened on the friction surfaces of the embedded rail parts. The static friction force generated can achieve vertical locking of the ship-bearing compartment. However, on the one hand, too many tensioning cylinders will lead to an increased failure rate of the equipment. At the same time, due to the limited space in the tower column groove, the cylinder bodies of the tensioning cylinders are all set in the guide grooves on the locking frame and are difficult to remove directly. When inspecting or replacing the tensioning cylinders, it is necessary to dismantle the entire docking locking device and lift it out of the tower column groove, which makes inspection and maintenance more difficult. Utility Model Content

[0004] The purpose of the utility model is to overcome the defects of the existing technology and provide a hydraulic two-way tightening ship lift ship compartment docking and locking device, in which the tightening cylinder and the locking pin are arranged separately, and the tightening cylinder is arranged in the gap between the two locking pins. It is not only convenient to disassemble and assemble the tightening cylinder, but also a tightening cylinder in the same group of guide components acts on the locking pins on both sides at the same time, which greatly reduces the number of tightening cylinders required and reduces the workload of maintenance and overhaul.

[0005] The purpose of this utility model is achieved through the following technical solutions:

[0006] A hydraulic bidirectional tightening ship lift cabin docking and locking device comprises a locking frame and a plurality of guide assemblies arranged in the locking frame, each group of guide assemblies comprising guide grooves located on the left and right sides of the locking frame, the plurality of guide assemblies being arranged in the vertical direction, locking pins being provided in the guide grooves on the left and right sides, an installation gap between the locking pins in the same group of guide assemblies and a tightening oil cylinder being provided in the installation gap, the two ends of the tightening oil cylinder being respectively hinged to the locking pins on both sides thereof, the two ends of the tightening oil cylinder being able to extend or retract in the horizontal direction so as to allow the end face of the locking pin to contact or separate with the rail embedded parts in the groove of the tower column.

[0007] In one embodiment, the locking frame is composed of a top plate, a bottom plate and multiple vertical plates, each of the vertical plates is provided with a through hole for the installation of the guide groove, and the multiple vertical plates are all located in the area outside the installation gap. Through this embodiment, the vertical plates of the locking frame avoid the tightening cylinder and at the same time provide a through hole for the installation of the guide groove, which is convenient for removing or installing the tightening cylinder from the side when disassembling and assembling the tightening cylinder.

[0008] In one embodiment, the guide grooves in each group of the guide assemblies are symmetrically arranged along the vertical center line of the locking frame. Through this embodiment, the locking pins in the guide grooves can maintain synchronous operation, that is, when the docking and locking operation is performed on the ship compartment, the locking pins on both sides of the tightening cylinder are synchronously extended from the side and tightened on the rail friction surface.

[0009] In one embodiment, a limiting portion is further provided at one end of the guide grooves in the same group of the guide assemblies that are close to each other. Through this embodiment, the provided limiting portion can control the retraction position of the locking pin when the support cabin is contacted and locked, thereby solving the problem of the locking pins on both sides of the tightening cylinder retreating asynchronously even if they are asynchronous due to the difference in retraction resistance, and ensuring that when the tightening cylinder retreats, the locking pins on both sides can retreat and disengage from the friction surface one after another.

[0010] In one embodiment, the limiting portion is an annular structure, which is fixed at the end of the guide groove, and its inner diameter is smaller than the diameter of the locking pin. Through this embodiment, the locking pin is limited by blocking the locking pin with the inner diameter of the limiting portion.

[0011] In one embodiment, the locking pin includes a connecting seat and a pin shaft, a weight-reducing cavity is opened at one end of the pin shaft, one end of the connecting seat is connected to the weight-reducing cavity, and the other end is hinged to the tightening cylinder. Through this embodiment, the weight-reducing cavity opened at one end of the pin shaft facilitates reducing the weight of the locking pin, facilitates the driving of the tightening cylinder, and also facilitates the connection of the connecting seat.

[0012] In one embodiment, a spherical groove is provided at one end of the locking pin away from the weight-reducing cavity, a ball head assembly is installed on the spherical groove, and a friction plate is provided on the side of the ball head assembly away from the weight-reducing cavity, and the friction plate is used to contact or separate with the rail embedded parts. Through this embodiment, a ball head assembly is provided on the spherical groove of the locking pin, and a friction plate is installed on it, so that the friction plate can rotate within a certain degree. When the locking pin is extended and tightened, the friction plate can automatically adapt to the rail friction surface, thereby ensuring stability during the docking and locking operation of the ship carriage.

[0013] In one embodiment, it further includes longitudinal guide wheel assemblies arranged at the top and bottom of the locking frame, the longitudinal guide wheel assemblies are in contact with the longitudinal rail embedded parts in the tower column groove, and the longitudinal guide wheel assemblies have springs extending in the horizontal direction.

[0014] In one embodiment, it further comprises a plurality of transverse guide wheels provided on the side walls of the locking frame, wherein the transverse guide wheels are in contact with transverse rail embedded parts provided on the bottom of the tower column groove.

[0015] In one embodiment, a gas spring mounting beam is further provided on the vertical plate, an inclined gas spring is hinged to the middle part of the gas spring mounting beam, and a supporting oil cylinder is hinged to the bottom of the locking frame. Both the gas spring and the supporting oil cylinder are used to be hinged to the ship supporting chamber. Through this embodiment, the gas spring mounting beam is provided on the vertical plate, which is not only convenient for removing the gas spring mounting beam, but also convenient for disassembling and assembling the locking pin in the locking frame.

[0016] The beneficial effects of the present invention are:

[0017] (1) A locking pin is hinged at each end of a tightening cylinder. When the tightening cylinder is pushed out, the locking pins on both sides are pushed to tighten against the friction surfaces on both sides. The mechanism relies on static friction to achieve locking relative to the friction surfaces. That is, the tightening cylinder and the locking pin are set separately, and the tightening cylinder is set in the gap between the two locking pins. This not only makes it convenient to disassemble and assemble the tightening cylinder, but also greatly reduces the number of tightening cylinders required, reducing the workload of maintenance and overhaul.

[0018] (2) The limit portion provided can prevent the locking pins from retracting asynchronously due to the difference in retraction resistance, and ensure that when the tensioning cylinder retracts, the locking pins on both sides can be retracted and separated from the friction surface in turn, that is, the locking pin with the smaller retraction resistance on both sides of each tensioning cylinder retracts first until it is restricted by the limit ring, and then the other locking pin retracts. When all the locking pins are retracted, the vertical lock of the ship compartment is released. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0028] The present invention will be further described below with reference to the accompanying drawings.

[0029] The utility model provides a hydraulic two-way tightening ship lift cabin docking and locking device. Figure 1 As shown, it includes a locking frame 1 and multiple groups of guide assemblies arranged in the locking frame 1, each group of guide assemblies includes guide grooves 1a located on the left and right sides of the locking frame 1, and the multiple groups of guide assemblies are arranged in the vertical direction. Locking pins 2 are provided in the guide grooves 1a on the left and right sides. There is an installation gap between the locking pins 2 in the same group of guide assemblies, and a tightening cylinder 3 is provided in the installation gap. The two ends of the tightening cylinder 3 are respectively hinged to the locking pins 2 on both sides thereof. The two ends of the tightening cylinder 3 can be extended or retracted in the horizontal direction to allow the end faces of the locking pins 2 to contact or separate with the track embedded parts in the tower column groove 10;

[0030] It should be noted that if Figure 1As shown, a locking pin 2 is hinged at each end of a tightening oil cylinder 3. When the tightening oil cylinder 3 is pushed out, the locking pins 2 on both sides are pushed to tighten against the friction surfaces on both sides. The mechanism achieves locking relative to the friction surfaces by relying on static friction force, that is, the tightening oil cylinder 3 and the locking pin 2 are separately provided. At the same time, the tightening oil cylinder 3 is provided in the gap between the two locking pins 2, which not only facilitates the disassembly and assembly of the tightening oil cylinder 3, but also greatly reduces the number of tightening oil cylinders 3 required, reducing the workload of maintenance and overhaul.

[0031] In one embodiment, Figure 1 and Figure 2 As shown, the locking frame 1 is composed of a top plate, a bottom plate, and a plurality of vertical plates. Each vertical plate is provided with a through hole for installation of the guide groove 1a. The plurality of vertical plates are all located outside the installation gap. That is, the vertical plates of the locking frame 1 avoid the tensioning cylinder 3 and provide a through hole for installation of the guide groove 1a. This facilitates the removal or installation of the tensioning cylinder 3 from the side when removing or installing the tensioning cylinder 3.

[0032] In one embodiment, the guide grooves 1a in each guide assembly are symmetrically arranged along the vertical centerline of the locking frame 1, so that the locking pins 2 in the guide grooves 1a can maintain synchronous operation. That is, when the docking and locking operation of the carrier is performed, the locking pins 2 on both sides of the tightening cylinder 3 are synchronously extended from the side and tightened on the rail friction surface 11a.

[0033] In one embodiment, a limiting portion 4 is further provided at one end of the guide grooves 1a in the same group of guide assemblies that is close to each other, that is, the limiting portion 4 is capable of controlling the retraction position of the locking pin 2 when the ship carriage is contacted and locked, thereby solving the problem that the locking pins 2 on both sides of the tightening cylinder 3 retract asynchronously even when they are asynchronous due to the difference in retraction resistance, and ensuring that when the tightening cylinder 3 retracts, the locking pins 2 on both sides can be retracted and separated from the friction surface in succession, that is, the one with the smaller retraction resistance on both sides of each tightening cylinder 3 retracts first until it is restricted in movement by the limiting ring, and then the other locking pin 2 retracts. When all the locking pins 2 are retracted, the ship carriage is released from vertical locking.

[0034] Specifically, the limiting portion 4 is an annular structure, which is fixed to the end of the guide groove 1a, and its inner diameter is smaller than the diameter of the locking pin 2, that is, the locking pin 2 is limited by blocking the locking pin 2 with the inner diameter of the limiting portion 4;

[0035] In one embodiment, Figure 3 As shown, the locking pin 2 includes a connecting seat 2b and a pin shaft 2a. A weight-reducing cavity is provided at one end of the pin shaft 2a. One end of the connecting seat 2b is connected to the weight-reducing cavity, and the other end is hinged to the tensioning cylinder 3. The weight-reducing cavity provided at one end of the pin shaft 2a helps reduce the weight of the locking pin 2, facilitates the driving of the tensioning cylinder 3, and also facilitates the connection of the connecting seat 2b.

[0036] Furthermore, a spherical groove is formed at one end of the locking pin 2 away from the weight-reducing cavity, on which a ball head assembly 2c is mounted. A friction plate 2d is provided on the side of the ball head assembly 2c away from the weight-reducing cavity. The friction plate 2d is used to contact or separate with the rail embedded component. That is, the ball head assembly 2c is provided on the spherical groove of the locking pin 2, and the friction plate 2d is mounted thereon, so that the friction plate 2d can rotate within a certain range. When the locking pin 2 is extended and tightened, the friction plate 2d can automatically adapt to the rail friction surface 11a, thereby ensuring stability during the docking and locking operation of the carrier.

[0037] In one embodiment, Figure 1 and Figure 4 As shown, the locking frame 1 further includes longitudinal guide wheel assemblies 5 disposed at the top and bottom thereof, the longitudinal guide wheel assemblies 5 being in contact with longitudinal track embedded parts 11 in the tower column groove 10, the longitudinal guide wheel assemblies 5 having springs extending in the horizontal direction, and a plurality of transverse guide wheels 6 disposed on the side walls of the locking frame 1, the transverse guide wheels 6 being in contact with transverse track embedded parts 12 provided on the bottom of the tower column groove 10;

[0038] In one embodiment, Figure 1 and Figure 4 As shown, a gas spring 8 mounting beam is further provided on the vertical plate, an inclined gas spring 8 is hingedly connected to the middle of the gas spring 8 mounting beam, and a supporting oil cylinder 7 is further hingedly connected to the bottom of the locking frame 1. The gas spring 8 and the supporting oil cylinder 7 are both used to be hinged to the ship carrier, that is, the gas spring 8 mounting beam is provided on the vertical plate, which is not only convenient for removing the gas spring 8 mounting beam, but also convenient for disassembling and installing the locking pin 2 in the locking frame 1;
