Description

Technical Field

[0001] The utility model relates to the technical field of mechanical equipment, in particular to a novel jacking mechanism. Background Art

[0002] In the fields of mechanical processing, jacking devices are often needed to lift workpieces. The existing jacking mechanisms still have certain defects when used, such as:

[0003] In the prior art, the lifting stroke is limited by the length of the lifting mechanism itself, which is limited in use when long-distance lifting is required and cannot meet the needs of long-distance lifting.

[0004] In view of this, it is necessary to provide a new type of jacking mechanism to solve or at least alleviate the above technical defects. Utility Model Content

[0005] The main purpose of the utility model is to provide a jacking mechanism, aiming to solve the technical problem that the jacking mechanism in the prior art cannot achieve long-distance jacking.

[0006] To achieve the above-mentioned purpose, the utility model provides a new jacking mechanism, including: a base, a jacking plate is arranged above the base, and a jacking drive part is arranged between the jacking plate and the base, and a limiting part is also arranged between the jacking plate and the base, and the limiting part includes a column, a support plate and a limiting rod, the column is vertically arranged on the upper end surface of the base, the support plate is installed on the head end of the column, the limiting rod is installed on the upper end surface of the support plate, and the head end of the limiting rod is connected to the jacking plate.

[0007] The design of the base plays a role in fixed support for the entire device. The jacking plate is used to support the workpiece and lift the workpiece. The design of the jacking drive part is the driving source of the jacking plate, which is used to drive the jacking plate to move vertically and parallel. The design of the limit part plays a role in limiting the movement of the jacking plate. At the same time, the jacking plate is erected above the driving source, thereby increasing the stroke mechanism of the jacking plate, specifically three times the stroke of the driving source. The support plate is erected above the base through a column, and the support plate and the jacking plate are connected by a limit rod, which plays a role in limiting the movement of the jacking plate.

[0008] Preferably, the lifting drive part includes a driving source, a connecting member and a connecting rod. The driving source is vertically arranged on the upper end surface of the base, the connecting member is installed on the output shaft of the driving source, the connecting rod is arranged on the upper end surface of the base, located on both sides of the driving source, and the head end of the connecting rod is connected to the lower end surface of the lifting plate, and the connection between the connecting rod and the base and the lifting plate are all hinged.

[0009] The connecting rod adopts the existing telescopic structure available on the market in this field. In actual use, the driving source drives the connecting rod to be extended and retracted through the connecting piece, thereby performing a jacking process on the workpiece on the upper end of the jacking plate.

[0010] Preferably, the driving source is one of a cylinder, a hydraulic rod or an electric push rod.

[0011] The cylinder, hydraulic rod or electric push rod all adopt the existing structure on the market. This method is common knowledge in this field, so it will not be described in detail.

[0012] Preferably, three groups of columns are arranged at equal intervals on the upper end surface of the base, and the connections between the columns, the base and the support plate are all welded.

[0013] The design of three groups of columns ensures the stability of the fixed support of the support plate, and the welding design ensures the stability of the connection between the columns, the base and the support plate.

[0014] Preferably, the area of ​​the support plate is larger than that of the base, and a cavity for the movement of the lifting drive unit is preset on the support plate.

[0015] The center point of the cavity corresponds to the center point of the driving source, thereby ensuring the normal activity of the jacking drive part and further ensuring the normal use of the device.

[0016] Preferably, two groups of the limiting rods are symmetrically arranged on the end surface of the support plate, and the limiting rods are telescopic structures.

[0017] The telescopic limit rod is an existing structure on the market in this field. The design of two sets of telescopic limit rods ensures the stability of the connection between the support plate and the lifting plate.

[0018] Preferably, a protective mechanism is also included, which includes a mounting hole and a protective block. The mounting hole is preset on the upper end surface of the jacking plate, and the protective block is detachably arranged in the mounting hole. Two groups of mounting holes and protective blocks are symmetrically arranged on the jacking plate.

[0019] The mounting hole and the protective block can be fixed by bolts, and the mounting hole and the protective block can also be connected by threads to form a detachable structure. The design of the protective block prevents the workpiece from falling from the lifting plate.

[0020] The beneficial effects of the utility model are:

[0021] 1. When the utility model is in use, the design of the limiting part plays a role in limiting the movement of the lifting plate. At the same time, the lifting plate is set above the driving source, thereby increasing the stroke mechanism of the lifting plate, specifically three times the stroke of the driving source, thereby making it convenient for users to lift the workpiece over a long distance according to actual needs, which is conducive to its popularization and use.

[0022] 2. When the utility model is in use, a protective mechanism is provided when the workpiece is at the upper end of the jacking plate to prevent the workpiece from falling from the jacking plate during jacking. The protective block in the protective mechanism is detachable, which is convenient for the user to regularly replace and maintain the protective block, reflecting the practicality of the device.
