Description

Technical Field

[0001] This utility model relates to the field of anchoring technology for gantry cranes, specifically to an anchoring device based on a worm gear screw jack. Background Technology

[0002] In the application scenarios of gantry cranes, the working states of gantry cranes are mainly divided into four types: hoisting, luffing, slewing, and traveling, as shown in the attached diagram. Figure 10 As shown, in rotating operation, the turntable and above of the gantry crane are connected to the fixed part of the gantry via a slewing bearing, allowing relative rotation. In non-operating conditions, due to wind force, the turntable and above will also rotate relative to the fixed part of the gantry. Typically, a rotational braking torque is provided by de-energizing the brake wheel using the rotating mechanism brake. However, braking solely through the rotating mechanism brake cannot effectively guarantee braking performance, and the risk of the turntable and above rotating remains.

[0003] Therefore, anchoring devices are usually needed to ensure that the gantry crane is in a relatively stable state in order to avoid the impact of natural forces such as typhoons, rainstorms, and earthquakes.

[0004] While common lever-based rotating anchoring devices can achieve anchoring, the linkage system must be designed with multiple connecting rods and pins to ensure normal operation. Due to the increased number of hinge points, corrosion at these hinge points can make lifting more difficult during later use.

[0005] Therefore, there is an urgent need for an anchoring device based on a worm gear screw jack to solve the anchoring problem between the turntable and the above part of the gantry crane and the fixed part of the gantry. Utility Model Content

[0006] This utility model addresses the shortcomings of existing technologies by providing an anchoring device based on a worm gear screw jack to solve the anchoring problem between the turntable and the upper part of a gantry crane and the fixed part of the gantry frame.

[0007] To achieve the above objectives, the present invention adopts the following technical solution: An anchoring device based on a worm gear screw jack includes an anchoring plate, an anchoring pin, a worm gear screw jack, and a chain. The anchoring plate is installed on the upper side of the fixed part of the gantry and has anchoring holes. The worm gear screw jack is installed on the lower side of the turntable and above, with the output end of the worm gear screw jack facing downward and connected to one end of the chain. The other end of the chain is connected to the anchoring plate. The worm gear screw jack is used to drive the chain to move the anchoring plate downward to insert into the anchoring hole, or upward to move away from the anchoring hole.

[0008] To optimize the above technical solution, the specific measures also include: Furthermore, the output end of the worm gear screw jack is equipped with an upper connecting seat, which is used to connect the upper end of the chain.

[0009] Furthermore, the end of the chain away from the worm gear screw jack is connected to a lower connecting seat, which is used to connect to the upper end of the anchor plate.

[0010] Furthermore, a flange plate is installed at the lower end of the lower connecting seat, and the flange plate is used to connect to the upper end of the anchor plate.

[0011] Furthermore, a guide sleeve is installed on the side of the turntable and the portion above it, and the anchoring pin is slidably disposed in the guide sleeve.

[0012] Furthermore, the worm gear screw jack adopts a hand-cranked worm gear screw jack.

[0013] Furthermore, the lower end of the anchoring pin is constricted from top to bottom.

[0014] Furthermore, the anchoring pin has a structure that is wide at both ends and narrow in the middle.

[0015] Furthermore, the upper end of the anchoring hole of the anchoring plate is flared from bottom to top.

[0016] Furthermore, it also includes a laser receiving sensor and a laser transmitter, both of which are installed at the lower end of the anchor plate and located on opposite sides of the anchor hole. The laser transmitter is used to continuously send laser signals to the laser receiving sensor, and the laser receiving sensor is electrically connected to the worm gear screw jack.

[0017] The beneficial effects of this utility model are: This invention utilizes an anchoring plate on the upper side of the fixed part of the gantry crane's frame, in conjunction with a worm gear screw jack on the side of the turntable and above of the gantry crane, and an anchoring pin connected to the worm gear screw jack by a chain below the worm gear screw jack. This allows for anchoring between the turntable and above of the gantry crane and the fixed part of the frame when needed. Specifically, after the turntable and above of the gantry crane rotates to a designated position, the worm gear screw jack drives the anchoring pin to descend and insert into the anchoring hole, ensuring effective anchoring between the turntable and above of the gantry crane and the fixed part of the frame. The chain provides greater freedom of movement and reduces the impact on other structures caused by the excessive speed at which the worm gear screw jack starts. It also avoids the problem of multi-section connecting rod pins being difficult to lift due to hinge point corrosion.

[0018] This utility model device can ensure that the turntable and above do not rotate relative to the fixed part of the gantry. It has a simple structural layout, simple parts manufacturing, and strong practicality. This device adopts the most direct vertical lifting form, reduces other mechanical structures, and improves efficiency. Attached Figure Description

[0021] The present invention will now be described in detail with reference to the accompanying drawings.

[0022] As attached Figure 1 and attached Figure 2As shown in the figure, an anchoring device based on a worm gear screw jack according to an embodiment of the present invention includes an anchoring plate 3, an anchoring pin 5, a worm gear screw jack 1, and a chain 2. The anchoring plate 3 is installed on the upper side of the gantry fixing part 11, and the anchoring plate 3 is provided with an anchoring hole. The worm gear screw jack 1 is installed on the lower side of the turntable and above part 9. The output end 1021 of the worm gear screw jack 1 is set downward and connected to one end of the chain 2. The other end of the chain 2 is connected to the anchoring plate 3. The worm gear screw jack 1 is used to drive the chain 2 to carry the anchoring plate 3 to move downward and insert into the anchoring hole, or to move upward and away from the anchoring hole.

[0023] This invention utilizes an anchoring plate 3 on the upper side of the gantry frame fixing part 11 of a gantry crane, in conjunction with a worm gear screw jack 1 on the side of the turntable and above part 9 of the gantry crane, and an anchoring pin 5 connected to the worm gear screw jack 1 below by a chain 2. This allows for anchoring between the turntable and above part 9 of the gantry crane and the gantry frame fixing part 11 when needed. Specifically, after the turntable and above part 9 of the gantry crane rotates to a designated position, the worm gear screw jack 1 drives the anchoring pin 5 to descend and insert into the anchoring hole, ensuring effective anchoring between the turntable and above part 9 of the gantry crane and the gantry frame fixing part 11. The chain 2 provides greater freedom of movement and reduces the impact on other structures caused by the excessive speed at which the worm gear screw jack 1 starts. It also avoids the problem of multiple connecting rod pins being difficult to lift due to hinge point corrosion.

[0024] In specific implementation environments, the design of the chain 2 structure can reduce the number of hinge points on the structure. During use, when hinge points are prone to corrosion, it makes the lifting operation of the device increasingly difficult. The chain 2 structure can effectively avoid the impact of corrosion and other phenomena.

[0025] In this solution, the worm gear screw jack 1 is an existing device. When in use, the output end 1021 of the screw 102 on the worm gear screw jack 1 moves up and down by the forward and reverse rotation of the motor 101 of the worm gear screw jack 1, thereby driving the chain 2 to carry the anchor plate 3 to move up away from the anchor hole, or to move down and insert into the anchor hole.

[0026] As attached Figure 3 As shown, in this embodiment, the worm gear screw jack 1 can be mounted on the side of the turntable and above the part 9 via the support 7.

[0027] The outer side of the slewing bearing 10 of the gantry crane can be fixed relative to the fixed part 11 of the gantry frame.

[0028] As attached Figure 5 As shown, in another specific embodiment based on the above, the output end 1021 of the worm gear screw jack 1 is equipped with an upper connecting seat, which is used to connect the upper end of the chain 2.

[0029] In another specific embodiment based on the above, the end of the chain 2 away from the worm gear screw jack 1 is connected to a lower connecting seat, which is used to connect to the upper end of the anchor plate 3.

[0030] The lower end of the aforementioned lower connecting seat is equipped with a flange plate 8, which is used to connect to the upper end of the anchor plate 3. In this design, the upper end of the anchor pin 5 can be provided with a threaded hole, and it can be detachably connected to the flange plate 8 by bolts or the like, providing convenient disassembly and replacement.

[0031] In another specific embodiment based on the above, a guide sleeve is also installed on the side of the turntable and the portion above it 9, and the anchoring pin 5 is slidably disposed in the guide sleeve. In this way, the anchoring pin 5 can be protected during daily use and guided during movement via the guide sleeve.

[0032] As attached Figure 4 As shown, in another specific embodiment based on the above, the worm gear screw jack 1 is a hand-cranked worm gear screw jack. The hand-cranked worm gear screw jack is an existing device. In this solution, the screw 102 can be driven by either the motor 101 or the rocker arm 103 on the hand-cranked worm gear screw jack, as needed.

[0033] In the above embodiments, the motor 101 and rocker arm 103 can be selected as needed. The worm gear screw jack 1 is based on the movement of the worm gear and is driven by the motor 101 or rocker arm 103. The screw 102 moves up or down to achieve linear displacement of the load, that is, to drive the anchor pin 5 to move up and down.

[0034] In another specific embodiment based on the above, the lower end of the anchor pin 5 is constricted from top to bottom.

[0035] As attached Figure 7 As shown, in another specific embodiment based on the above, the anchoring pin 5 has a structure that is wide at both ends and narrow in the middle.

[0036] As attached Figure 8 and attached Figure 9 As shown, in another specific embodiment based on the above, the upper end of the anchoring hole of the anchoring plate 3 is flared from bottom to top. In this embodiment, it can cooperate with the anchoring pin 5, whose lower end is constricted from top to bottom, to form a flow guiding structure, allowing the anchoring pin 5 to smoothly enter the anchoring hole within the range of falling and shaking, avoiding the situation where the anchoring pin 5 cannot fall into the anchoring hole due to shaking, and facilitating convenient operation by a single person.

[0037] As attached Figure 6As shown, in another specific embodiment based on the above, a laser receiving sensor 4 and a laser transmitter 6 are also included. Both the laser receiving sensor 4 and the laser transmitter 6 are installed at the lower end of the anchor plate 3 and are located on opposite sides of the anchor hole. The laser transmitter 6 is used to continuously send laser signals to the laser receiving sensor 4. The laser receiving sensor 4 is electrically connected to the worm gear screw jack 1.

[0038] Therefore, during use, when the anchor pin 5 falls to the designated position and forms an anchored state, the anchor pin 5 blocks the laser emitted by the laser emitter 6, and the laser receiving sensor 4 correspondingly controls the drive device to pause, waiting for manual restart. When the anchor pin 5 is raised, the laser receiving sensor 4 can receive the laser, thus not controlling the drive device and waiting for triggering normally. During use, the anchoring status can be remotely or automatically determined by whether the laser can be received, and the hoist can be controlled to rise or fall, achieving remote automatic control. In this solution, it can also be connected to an automation system as needed to achieve automatic one-click anchoring.

[0039] This utility model device can ensure that the turntable and above part 9 and the fixed part of the gantry do not rotate relative to each other. The structure is simple, the parts are easy to manufacture, and it is highly practical. This device adopts the most direct vertical lifting form, reduces other mechanical structures, and improves efficiency. The setting of the chain 2 gives the device more degrees of freedom and reduces the impact on other structures at the moment of starting the worm gear screw jack 1. At the same time, it avoids the problem of multi-section connecting rod pins being difficult to lift due to hinge point corrosion.
