Abstract
The invention discloses a lifting device capable of measuring the force. The lifting device comprises sliding blocks, linear guiding rails, a lifter, a nut, a pressure sensor, installing racks, a connecting frame and two proximity switches. The pressure sensor is fixedly connected with the nut. The nut is matched with a lead screw and does linear motion along the lead screw. The two linear guiding rails are vertically arranged on the installing racks which are located on the two sides of the lifter. The lead screw is sleeved with a protrusion on the inner surface of the connecting frame, and the protrusion on the inner surface of the connecting frame is placed on the upper surface of the pressure sensor. The left end and the right end of the connecting frame are fixedly connected with the sliding blocks arranged on the linear guiding rails respectively. The two proximity switches are arranged in the limiting positions of the lifter. Heavy materials are arranged on the outer surface of the connecting frame. According to the lifting device capable of measuring the force, size changes of the load can be measured in the lifting process; the lifter can be stopped automatically when lifted to the limiting positions; the structure is simple, and the lifting precision is high; lifting is smooth and steady, force measurement is reliable, and the device is especially applied to using occasions where the force is measured in the lifting process under the conditions of unbalance loading and small space of mechanism arrangement.
Description
Technical field
The invention belongs to engineering lifting field, be specifically related to a kind of can the jacking system of dynamometry in lifting process.
Background technology
The mode that general lifting is relatively commonly used has: carry out lifting, the direct lifting of electric cylinder etc. by hydraulic-driven scissors mechanism.When needs lifting is higher, general with the lifting of hydraulic-driven scissor, but this mode is not suitable for the situation of load unbalance loading, and the easy leakage of oil of hydraulic pressure; And not only cost is higher by the direct lifting of electric cylinder, if while with multiple electric cylinder load unbalance loading, sensing lead change becomes again more difficult.
Summary of the invention
The object of this invention is to provide a kind of can the jacking system of dynamometry, adopt driven by motor, there is not Leakage; There is good comformability for unbalance loading, load variations in lifting process can be convenient for measuring, precision is high, effectively can make up the deficiency that existing apparatus exists.
Technical scheme of the present invention is: a kind of can the jacking system of dynamometry, it is characterized in that: comprise slide block 2, line slideway 1, elevator 3, nut 4, pressure sensor 6, erecting frame 8, link span 9 and two proximity switches 7;
Pressure sensor 6 is fixedly connected with nut 4, and nut 4 coordinates with leading screw and does straight-line motion along leading screw; Article two, line slideway is vertically arranged on the erecting frame of the elevator left and right sides, and the projection of link span 9 inside face to be enclosed within leading screw and to be positioned over the upper surface of pressure sensor, and the two ends, left and right of link span are fixedly connected with the slide block 2 be arranged on line slideway respectively; Two proximity switches are separately positioned on the high-low limit position of elevator; Weight is arranged on the outside face of link span.
Beneficial effect: the present invention can realize the measurement of load change in lifting process; Can automatically stop to during end position in lifting; Structure is simple, and lifting precision is high.The present invention is elevated steadily, and precision is high, and dynamometry is reliable, is particularly being applicable to the lifting use occasion with dynamometry under unbalance loading, the less situation in arrangement of mechanism space.

Detailed description of the invention
For making object of the present invention, content and advantage clearly, below in conjunction with drawings and Examples, the specific embodiment of the present invention is described in further detail.
As Figure 1-4, the invention provides a kind of can the jacking system of dynamometry, comprise slide block 2, line slideway 1, elevator 3, nut 4, rebound 5, pressure sensor 6, erecting frame 8, link span 9, two proximity switches 7;
Pressure sensor 6 is fixedly connected with nut 4 by rebound 5, and nut 4 coordinates with leading screw and does straight-line motion along leading screw;
Article two, line slideway 1 is vertically arranged on the erecting frame of the elevator left and right sides, for guiding, the projection of link span 9 inside face to be enclosed within leading screw and to float and is placed in the upper surface of pressure sensor, and the two ends, left and right of link span are fixedly connected with the slide block 2 be arranged on line slideway respectively; Two proximity switches are separately positioned on the high-low limit position of elevator; Weight is arranged on the outside face of link span, and in the process of up-and-down movement, pressure sensor can the change of sensed pressure, determines whether weight arrives control position; Meanwhile, link span, along guide rail movement, can offset the moment of flexure that unbalance loading causes elevator to greatest extent; At the proximity switch that end position is arranged, when being elevated to end position, can stop motion automatically.
The present invention is for needing the occasion measuring the stressed change of carrying object in lifting process.
