Description

Special loading and unloading hoisting machine for auxiliary road surface detection and coring equipment

technical field

The utility model relates to a loading and unloading hoisting machine, in particular to a special loading and unloading hoisting machine for auxiliary road surface on-site detection and coring equipment.

Background technique

In the process of road and bridge pavement construction, on-site pile foundation coring inspection has always been an important part of the whole process. Summer is the most favorable climate for pavement construction, and laboratory inspectors often face the risk of high temperature and heatstroke when they go to the site to conduct pile foundation coring inspection. In order to solve this problem, people take the coring equipment to be transported to the laboratory by construction transport vehicles for pile foundation coring testing. However, due to the heavy weight of the coring machine, four people are required to complete the lifting, loading and unloading, and pushing. During the high-frequency loading and unloading process, not only consumes a lot of physical strength, but also easily fails to lift, unbalanced, and easy to lift. Potential safety hazards such as collisions.

Contents of the invention

The purpose of the utility model is to provide a special loading and unloading hoisting machine for auxiliary road surface on-site detection and coring equipment.

In order to achieve the above object, the utility model takes the following technical solutions:

The special loading and unloading hoisting machine for auxiliary road surface on-site detection and coring equipment described in the utility model includes a base, a column, a boom and a lifting system; the column is composed of a first column welded with the base, and a lower end. The second column at the upper end of the first column is formed; the boom is composed of the first boom whose rear end is pinned to the top of the second column, and the first boom which is fitted in the front end of the first boom with a dynamic fit. It consists of two booms; the upper end of the second column is provided with a positioning plate, and the positioning plate is provided with a pin hole matching with the pin shaft of the positioning hole at the rear end of the first boom; the base is fixed on the channel steel by bolts, and the channel steel Welded to the upper surface of the horizontal backing plate.

The hoisting system is composed of a DC hoist and a hook device; the DC hoist is arranged on the first boom, and one end of the wire rope of the DC hoist turns around the fixed pulley arranged at the front end of the second boom, the The movable pulley of the hook device is fixedly connected with the second boom.

Positioning holes are arranged at intervals along the axial direction of the second boom, and pin holes cooperating with the pin shafts of the positioning holes on the second boom are opened on the first boom.

The utility model has the advantage that it is specially designed for solving the handling problem of pile foundation coring equipment. After adopting the utility model, the coring equipment can be stably loaded and landed safely only with the assistance of the testing personnel, which not only avoids possible damage to the coring equipment during the lifting process, but also ensures the safety of the testing personnel. At the same time, as shown in Figure 2, the boom is variable in elevation and telescopic, and can be folded at will for easy storage. The structure is compact and does not take up too much space, and the operation is simple, safe and reliable.

Detailed ways

The embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings. This embodiment is implemented on the premise of the technical solution of the present invention, and detailed implementation methods and specific operating procedures are provided, but the scope of protection of the present invention is not limited to the following Described embodiment.

As shown in Figure 1, the special loading and unloading hoisting machine for auxiliary road surface on-site detection and coring equipment described in the utility model includes a base 1, a column, a boom and a lifting system; the column is composed of a first column 2 welded with the base 1, It is composed of the second column 3 which is set on the upper end of the first column 2 in moving fit with the lower end. The first column 2 and the second column 3 are rotated and matched by double bearings 4; The boom 5 and the second boom 6 that is fitted in the front end of the first boom 5 in a moving fit are formed. Positioning holes 7 are arranged at intervals along the axial direction of the second boom 6 . The pin hole 8 matched with the pin shaft of the positioning hole 7 on the arm 6; the upper end of the second column 3 is provided with a positioning plate 9, and the positioning plate 9 is provided with a pin hole 10 matched with the pin shaft of the positioning hole pin at the rear end of the first boom 5; the base 1 is fixed on the channel steel 11 by bolts, and the channel steel 11 is welded on the upper surface of the horizontal backing plate 12.

The hoisting system consists of a DC hoist 13 and a hook device 14; the DC hoist 13 is arranged on the first boom 5, and one end of the steel wire rope 15 of the DC hoist 13 passes around the fixed pulley and the hook device arranged at the front end of the second boom 6 in turn. The movable pulley of 14 is fixedly connected with the second boom 6.

When the utility model is used, at first the horizontal backing plate 12 is placed on the engineering vehicle (such as a pickup truck) and clamped firmly, and then the base 1 is fixed on the channel steel 11 by bolts. According to the site conditions, adjust the length and elevation of the boom and fix it through the pin shaft. By rotating the boom, place the hook device above the coring equipment to lift and unload.
