Description

Technical Field

[0001] This utility model relates to the field of lifting equipment technology, and in particular to a lifting device for confined space. Background Technology

[0002] Due to limited air pressure under some bridge abutments and the low height of the ground above the bridge deck, traditional cranes cannot meet the requirements for lifting the bored piles and cannot be used for transportation. Furthermore, these types of equipment lack lifting limit devices, making them unstable. The lifting objects are manually removed near the opening, which can easily cause the objects to tip over, posing certain safety hazards. Utility Model Content

[0022] To make the objectives, technical solutions, and beneficial effects of this utility model clearer, the technical solutions of this utility model are further described below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of this utility model and are not intended to limit it.

[0023] See Figures 1 to 2 This utility model provides a lifting device for a confined space, erected on the ground 1, characterized in that the lifting device includes:

[0024] Two gantry frames 4 are provided on the ground 1. The ground 1 has multiple pre-embedded points 2 arranged from front to back, and support points 3 arranged between the pre-embedded points 2. The two gantry frames 4 are arranged at the corresponding pre-embedded points 2.

[0025] The traveling beam 5 is installed between the two gantry frames 4, and the traveling beam 5 is movably equipped with an electric hoist 6;

[0026] The support member is connected to the walking beam 5 and is set perpendicular to it.

[0027] In this embodiment, four pre-embedded points 2 are provided on the ground 1. Two gantry frames 4 are erected at intervals in the front-to-back direction within the corresponding pre-embedded points 2. A traveling beam 5 is erected between the two gantry frames 4. An electric hoist 6 is movably installed on the traveling beam 5. The electric hoist 6 travels along the traveling beam 5 to realize the lateral transportation of materials. In practical applications, the depth of the pre-embedded points 2 is pre-excavated according to the height of the ground 1 and the rail bridge surface, so that the height of the gantry frame 4 buried in the pre-embedded point 2 can be adjusted. Alternatively, when the working height is insufficient for lifting, a groove can be opened in the ground 1 between the two gantry frames 4 to meet the needs of hoisting and lateral transportation. On the other hand, the support is erected in the support point 3 and vertically connected to the traveling beam 5, providing additional stability and increasing the stability and rigidity of the traveling beam 5. This helps to distribute the load and reduce the deformation that may occur when the traveling beam 5 is hoisting heavy objects.

[0028] The traveling beam 5 is provided with two first installation notches 501, which are mounted on the corresponding gantry 4.

[0029] In this embodiment, two first mounting notches 501 are provided at opposite ends of the traveling beam 5. The two first mounting notches 501 are mounted on the corresponding gantry 4, so that the electric hoist 6 can distribute the weight on the corresponding gantry 4 during hoisting operations, thus ensuring the stability and safety of the traveling beam 5.

[0030] The walking beam 5 has a second installation notch 502 in the middle, and the support member passes through the second installation notch 502.

[0031] In this embodiment, the support member is connected through the second mounting notch 502. Since the support member is set perpendicular to the walking beam 5, the stability of the entire structure can be significantly enhanced. After the support member passes through the second mounting notch 502, it can more effectively distribute and bear the load from the walking beam 5, thereby reducing the deformation or displacement of the walking beam 5 caused by the suspension of heavy objects. By fixing the support member in the middle of the walking beam 5, not only can the overall rigidity and load-bearing capacity of the equipment be improved, but also the vibration and sway that may occur during operation can be effectively reduced, ensuring the safety and accuracy of operation.

[0032] The support member includes:

[0033] The crossbeam 7 is inserted through the second installation notch 502 in the left and right directions;

[0034] The support legs 8 are in a V-shape and are located on opposite sides of the crossbeam 7.

[0035] In this embodiment, the crossbeam 7 is fixed by the second mounting notch 502 in the middle of the traveling beam 5, so that the crossbeam 7 can be stably connected to the traveling beam 5 and can effectively distribute the load of the traveling beam 5. The lateral direction of the crossbeam 7 and the front-back direction of the two gantry 4 can evenly bear the load from the traveling beam 5, which enhances the overall rigidity and stability of the equipment. The outriggers 8 have a V-shaped structure and are located on opposite sides of the crossbeam 7. They can provide greater support force in a limited space, while maintaining the balance and stability of the structure to better resist lateral forces, thereby reducing structural swaying or displacement caused by external factors.

[0036] The outrigger 8 is equipped with a reinforcing crossbar 9.

[0037] In this embodiment, the reinforcing crossbar 9 and the outrigger 8 form a triangular structure to enhance the stability of the outrigger 8. The height of the two side outriggers 8 and the middle outrigger 8 can be adjusted according to the actual working space.

[0038] The pre-embedded point 2 and the support point 3 are provided with pre-embedded steel plates 10, and the gantry 4 and the support leg 8 are connected to the corresponding pre-embedded steel plates 10.

[0039] In this embodiment, the pre-embedded steel plate 10 is embedded in each pre-embedded point 2 and support point 3, and is laid flat with the ground 1 to ensure that the elevation is consistent, so as to ensure that the equipment is installed stably and is not easy to sink. If the ground 1 is relatively soft, hook reinforcement can be pre-embedded to ensure the stress.

[0040] The electric hoist 6 is equipped with a counterweight limiter.

[0041] In this embodiment, when the electric hoist 6 is loaded with material and lifted to a certain height, the hook collides with the counterweight limit switch, and the upper limit switch of the electric hoist 6 is opened. The LX series counterweight limit switch can be used, which has the characteristics of simple structure and convenient installation, and avoids accidents such as equipment damage caused by misoperation leading to the hook colliding with the electric hoist 6.

[0042] The gantry 4 is equipped with a ground-operated remote control 11.

[0043] In this embodiment, the equipment is operated using a ground-operated remote control 11, which allows for real-time observation of the situation inside the hoisting hole, the lifting of heavy objects, and the surrounding environment of the transportation channel during transportation, thus avoiding collisions caused by factors such as careless observation and blind spots during hoisting and transportation.

[0044] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this utility model without departing from the spirit and scope of the technical solutions of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
