Description

Technical Field

[0001] This utility model relates to the field of locking device technology, specifically to a gantry crane locking device. Background Technology

[0002] Gantry cranes are typically enormous in locations such as ports, construction sites, and factories. For example, gantry cranes used for loading and unloading containers in ports can reach heights and spans of tens of meters. In strong winds, without effective locking devices, the gantry crane may slide along the tracks due to the wind, causing equipment damage or even colliding with surrounding facilities, goods, or personnel, leading to serious safety accidents. Meanwhile, during non-working periods such as maintenance and upkeep, the locking devices ensure the gantry crane remains in a fixed position, facilitating operation by workers.

[0003] Currently, most commonly used gantry crane track locking devices employ a clamping locking structure, which uses clamping structures on both sides to grip the track, thereby achieving the locking function. However, these locking devices mostly use a two-point locking structure, and are only fixed on the left and right sides of the track, resulting in insufficient stability after locking. Therefore, those skilled in the art have provided a gantry crane track locking device to solve the problems mentioned in the background art. Utility Model Content

[0004] The purpose of this utility model is to provide a gantry crane track locking device to solve the above-mentioned technical problems.

[0005] The objective of this utility model can be achieved through the following technical solutions:

[0006] A gantry crane track locking device is applied to a track and includes a housing. The housing is disposed above the track, and two hydraulic cylinders are fixed inside the housing. The lower ends of the two hydraulic cylinders are connected to a locking component, which is used to lock with both sides of the track.

[0007] The locking assembly includes a connecting seat fixed to the extended end of the hydraulic cylinder. Both ends of the connecting seat are symmetrically rotatably connected to a clamping frame. A locking plate is fixedly connected to the lower end of the clamping frame. The locking plate is in contact with the track. The clamping frame is hinged to the outer end of the hydraulic cylinder.

[0008] The lower end of the hydraulic cylinder is also connected to a locking component two, which is used to lock with the upper end face of the track.

[0009] Furthermore, the locking component two includes a connecting seat two, which is arranged parallel to the track and fixedly connected to the connecting seat one. The outer end of the connecting seat two is rotatably connected to a clamping frame two, and the lower end of the clamping frame two is fixed with a locking sleeve. The locking sleeve is in contact with the track, and the clamping frame two is hingedly connected to the hydraulic cylinder.

[0010] Furthermore, the locking sleeve is in the shape of an inverted U and wraps around the outer end of the track;

[0011] Furthermore, the locking plate includes a fixing plate and a contact plate, the fixing plate being fixedly connected to the clamping frame, and the contact plate being in contact with the track and detachably connected to the fixing plate;

[0012] Furthermore, the outer end face of the fixing plate is provided with multiple cavities, and a movable block is slidably connected inside the cavity. The contact plate is fixedly connected to the movable block by screws.

[0013] Furthermore, a spring is provided inside the cavity, and the spring abuts against the movable block and the cavity;

[0014] Furthermore, the outer shell includes a main shell and a secondary shell. The secondary shell is fixed to the outside of the main shell near the locking component two. The lower ends of both the main shell and the secondary shell are set to an open state. Mounting plates are fixedly connected to both sides of the end of the main shell away from the secondary shell.

[0015] The beneficial effects of this utility model are:

[0016] 1. The present invention proposes a gantry crane locking device. This device is equipped with two sets of locking components. After installation, it can form a multi-point clamping and locking structure with strong stability, thereby effectively preventing the gantry crane from moving in non-working state, such as in the event of strong winds or other accidents, and ensuring the safe parking of the gantry crane.

[0017] 2. The gantry crane track locking device proposed in this utility model is equipped with a second locking component, which can simultaneously clamp the upper part of the track when the first locking component is locked. Through the friction between the locking sleeve and the track 1, the upper end is locked, which further improves the locking stability.

[0018] 3. The gantry crane track locking device proposed in this utility model has a split structure design for the locking plate, which is convenient for replacement after wear. At the same time, the movable block can slide in the cavity and is equipped with a spring, so that the contact plate is in the pop-out state before contacting the track.

[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present utility model.

[0028] Please see Figures 1 to 5 As shown, a gantry crane track locking device in this embodiment of the present invention is applied to a track 1 and includes a housing 2. The housing 2 is disposed above the track 1. Two hydraulic cylinders 3 are fixed inside the housing 2. The lower ends of the two hydraulic cylinders 3 are connected to locking components 4, which are used to lock with both sides of the track 1.

[0029] Specifically, the locking assembly 4 includes a connecting seat 41 fixed to the extended end of the hydraulic cylinder 3. Both ends of the connecting seat 41 are symmetrically rotatably connected to a clamping frame 42. The lower end of the clamping frame 42 is fixedly connected to a locking plate 43, which contacts the track 1. A connecting frame 44 is hinged between the clamping frame 42 and the outer end of the hydraulic cylinder 3. When the locking assembly 4 is in use, power is provided by the hydraulic cylinder 3. When the hydraulic cylinder 3 extends, the clamping frame 42 drives the locking plate 43 to tightly clamp the outer end of the track 1, using friction to prevent the gantry crane from moving. This device is equipped with two sets of locking assemblies 4. After installation, they can form a multi-point clamping and locking structure with strong stability, thereby effectively preventing the gantry crane from moving in non-working conditions, such as in strong winds or other unexpected situations, ensuring the safe parking of the gantry crane.

[0030] The locking plate 43 includes a fixing plate 431 and a contact plate 432. The fixing plate 431 is fixedly connected to the clamping frame 42, and the contact plate 432 contacts the track 1 and is detachably connected to the fixing plate 431. The locking plate 43 adopts a split structure design, and the contact plate 432, which is in direct contact with the track 1, can be disassembled for easy replacement after wear.

[0031] Specifically, the outer end face of the fixed plate 431 has multiple cavities 433. A movable block 435 is slidably connected inside the cavity 433. The contact plate 432 is fixedly connected to the movable block 435 by screws 436. A spring 434 is installed inside the cavity 433 and abuts against the movable block 435 and the cavity 433. The contact plate 432 is fixedly connected to the movable block 435 by screws 436. The contact plate 432 can be removed after the screws 436 are unscrewed. At the same time, the movable block 435 can slide in the cavity 433 and is equipped with a spring 434 so that the contact plate 432 is in a pop-out state before contacting the track 1. The elasticity of the spring 434 can play a buffering role to prevent mechanical collision and damage to the track 1.

[0032] Please see Figure 2 As shown, in one embodiment of this utility model, a locking component 2 5 is also connected to the lower end of a hydraulic cylinder 3. The locking component 2 5 is used to lock with the upper end surface of the track 1.

[0033] Specifically, locking component 2 5 includes connecting seat 2 51, which is parallel to the track 1 and fixedly connected to connecting seat 1 41. A clamping frame 2 52 is rotatably connected to the outer end of connecting seat 2 51. A locking sleeve 53 is fixed to the lower end of clamping frame 2 52. The locking sleeve 53 contacts the track 1. A connecting frame 2 54 is hinged between clamping frame 2 52 and hydraulic cylinder 3. Locking component 2 5 can clamp the upper part of the track 1 simultaneously when locking component 1 4 is locked. Through the friction between locking sleeve 53 and track 1, the upper part is locked, which further improves the locking stability.

[0034] Among them, the locking sleeve 53 is in the shape of an inverted U and wraps around the outer end of the track 1. The contact area between the locking sleeve 53 and the track 1 is large, the friction torque is large, and the stability is strong.

[0035] Please see Figure 1 As shown, in one embodiment of the present invention, the outer shell 2 includes a main shell 21 and a secondary shell 23. The secondary shell 23 is fixed on the outside of the main shell 21 near the locking component 5. The lower ends of both the main shell 21 and the secondary shell 23 are set to an open state. Mounting plates 22 are fixedly connected to both sides of the end of the main shell 21 away from the secondary shell 23.

[0036] The above description provides a detailed account of one embodiment of the present invention. However, this description is merely a preferred embodiment and should not be construed as limiting the scope of the present invention. All equivalent variations and improvements made within the scope of the claims of the present invention should still fall within the patent coverage of the present invention.
