Description

Movable manual gantry crane

Technical Field

The utility model relates to a structural design field specifically is a manual portal crane of movable, is applicable to manufacturing, processing, installation and the transportation of middle-size and small-size tool equipment.

Background

In the manufacturing, processing, installing and transferring processes of small and medium-sized tooling equipment, the difficulty of manual operation is high and the efficiency is low due to the weight, the shape, the special processing requirements and the like of the small and medium-sized tooling equipment, the small and medium-sized tooling equipment is limited by conditions of a production field, and large-sized hoisting equipment cannot be called for operation, so that great inconvenience is brought to the manufacturing, processing, installing and transferring work of the small and medium-sized tooling equipment.

Disclosure of Invention

At present, the gantry crane is mainly adopted in the market to carry out loading and unloading operations of outdoor goods yards, stock yards and bulk cargos, although the hoisting equipment has the characteristics of wide operation range and large hoisting capacity, the large hoisting equipment is very inconvenient to use and the cost is high due to the fact that small and medium-sized tooling equipment is manufactured, processed, installed and transported. In order to reduce the cost and greatly improve the production efficiency, the utility model provides a hoisting equipment-movable manual gantry crane which is suitable for the processing of small and medium-sized tooling equipment. The equipment not only simplifies the operation mode, but also is more flexible and convenient for larger hoisting equipment in the use process, greatly saves manpower and material resources, greatly improves the production efficiency, ensures the production period, and greatly improves the utilization rate of the tool due to the movable design.

The technical scheme of the utility model is that:

the movable manual gantry crane is characterized in that: comprises a main beam structure, a bracket, a lifting mechanism, a fetching device and a traveling mechanism;

the two ends of the main beam structure are fixedly provided with a support; the bottom of the bracket is provided with a travelling mechanism, and a locking device is arranged in the travelling mechanism and can lock the travelling mechanism; the main beams at the inner sides of the supports at the two ends are fixedly provided with lifting mechanisms, and the tail ends of the lifting mechanisms are provided with fetching devices.

Further preferred scheme, a manual portal crane of movable, its characterized in that: the main beam structure is made of 140I-shaped steel; the lifting mechanism adopts manual chain rewinding; the object taking device adopts a lock hook.

Advantageous effects

The utility model discloses not only simplify the operation mode, great type hoisting equipment is more nimble simultaneously in the use, and the material resources of using manpower sparingly greatly increase substantially production efficiency, guaranteed production cycle, portable design has improved the utilization ratio of frock greatly simultaneously.

1. The manual gantry crane is strong in mobility and small in occupied area, and can meet the requirements of manufacturing, processing, mounting and transferring of small and medium-sized tool equipment.

2. The manual gantry crane has wide operation range, can reduce manpower, reduce the production cost of units and greatly improve the working efficiency.

Additional aspects and advantages of the invention will be set forth in part in the description which follows and, in part, will be obvious from the description, or may be learned by practice of the invention.

Drawings

The above and/or additional aspects and advantages of the present invention will become apparent and readily appreciated from the following description of the embodiments, taken in conjunction with the accompanying drawings of which:

FIG. 1 is a schematic structural diagram of the present invention.

Detailed Description

The following detailed description of embodiments of the invention is intended to be illustrative, and not to be construed as limiting the invention.

The movable manual gantry crane in the embodiment comprises a main beam structure 1, a support 2, a lifting mechanism 3, a fetching device 4 and a traveling mechanism 5;

the main beam structure is made of 140I-shaped steel; the two ends of the main beam structure are fixedly provided with brackets; the bracket adopts a structure that two inverted triangles at two sides are combined with a transverse supporting rod at the middle part; the bottom of the bracket is provided with a travelling mechanism, and a locking device is arranged in the travelling mechanism and can lock the travelling mechanism; a lifting mechanism is fixedly arranged on the main beam at the inner sides of the brackets at the two ends, and the lifting mechanism adopts manual chain rewinding; the tail end of the lifting mechanism is provided with a material taking device which adopts a lock hook.

The movable manual gantry crane in the embodiment has light self weight, the maximum hoisting weight is about 3T, the main beam part is made of 140I-steel, and a manual chain block can be used for operating when materials are hoisted, so that the operation process is more flexible. Before the operation is started, fixing the manual gantry crane to prevent the gantry crane from sliding in the process of clamping materials to cause deviation of a clamping position; then the lock hook slides down to a certain height, the hoisted material is connected with a fetching device, and the material is conveyed to a preset position by using a lifting mechanism (manual chain reversing) to be welded, assembled and the like.

In the operation process, because will use steel to carry out welding operation and do not have driving a vehicle and mobile device in welding process to assist in a large number, need overturn the steel sheet to suitable angle and carry out seamless welding in whole welding process, the operation degree of difficulty is big, and manual operation is very inconvenient, and is inefficient, and the manufacturing cycle is too long, can't satisfy the task and issue the unit requirement. After the newly designed movable manual gantry crane is adopted, the cut steel plate is suspended through the movable gantry crane and assisted by one person beside the movable gantry crane, so that the steel plate to be welded ensures the machining angle, the welding precision is improved, and the quality of the tooling equipment is ensured.

Although embodiments of the present invention have been shown and described, it is to be understood that the above embodiments are exemplary and should not be construed as limiting the present invention, and that changes, modifications, substitutions and alterations can be made to the above embodiments by those of ordinary skill in the art without departing from the principles and spirit of the present invention.

Claims (2)
