Abstract
The utility model discloses a manufacturing tool for a lifter standard knot. The manufacturing tool for the lifter standard knot comprises an under frame, a free end support is installed at one end of the under frame in a rotatable mode, a fixed end support is installed at the other end of the under frame, connecting rods are connected between the free end support and the fixed end support, puller threaded rods are in screw fit with the four corners of the free end support respectively, a hand wheel is installed at the outer end of each puller threaded rod, and standard knot positioning blocks are installed in the positions, in the opposite direction of the puller threaded rods, of the fixed end support. Counterweight track movable positioning rods are arranged below the puller threaded rods in a sliding mode, springs are sleeved on the counterweight track movable positioning rods, and counterweight track positioning blocks are arranged in the positions, in the opposite direction of the counterweight track movable positioning rods, of the fixed end support. The manufacturing tool for the lifter standard knot can complete the manufacturing process of the construction lifter standard knot, and an original craft manufacturing process in which three set of craft devices are all operated manually to be finished is replaced.
Description
Technical field
The utility model is building hoist standard knot frock field, increases by two groups of counterweight guide rail location and electronic tumbler, has improved manufacture craft, has improved the standard knot quality, and then has improved security of products.
Background technology
Current building hoist is widely used in the various engineering constructions construction, and the quality of the quality of building hoist own is particularly important to its security in construction, GB GB/T10054 requires standard knot should guarantee interchangeability, the column faying face of adjacent standard knot is straight to scooping out during splicing, the jump that mutual dislocation forms.The cage guide rail is not more than 0.8mm, and the counterweight guide rail is not more than 0.5mm.Original cage guide rail (standard knot) adopts a cover frock making, and after the counterweight guide rail adopted another set of frock making to be shaped, assembly welding was to the cage guide rail again, and the result has formed standard knot, jump ratio that its dislocation forms is easier to control, and the jump that the counterweight guide rail forms difficulty have the situation under control.
The utility model content
The purpose of this utility model just provides a kind of lift standard knot and makes frock, can finish the manufacture craft device of building hoist standard knot, the technology production process that replaces former cause three cover process units all just can be finished by manually-operated.
In order to reach above-mentioned requirements, the scheme that the utility model adopts is:
The lift standard knot is made frock, include underframe, underframe one end is rotatablely equipped with the movable end support, the other end is equipped with the stiff end support, be connected with connecting rod between described movable end support and the stiff end support, four corners of movable end support have screwed togather fastening screw respectively, the outer end of fastening screw is equipped with handwheel, on the stiff end support of fastening screw relative direction the standard knot locating piece is installed, the fastening screw slid underneath is provided with counterweight track movement registration arm, be set with spring on the counterweight track movement registration arm, the stiff end support of counterweight track movement registration arm relative direction is provided with counterweight tracks positioned piece.
Described underframe both sides part is connected with support bar.
Described movable end back-end support is connected with motor by chain, and motor is connected with reductor, and reductor and movable end support chain are in transmission connection.
The utility model is existing to be improved primary standard joint frock, positioner at the newly-increased two groups of counterweight tracks of frock, being produced on the same frock of standard knot and counterweight guide rail finished, namely simplify operation and improved efficient again, the more important thing is the interchangeability that guarantees standard knot, guaranteed the precision of cage guide rail and counterweight guide rail again, the security that has improved complete machine, increase the electronic tumbler of a cover, alleviated labour intensity.
The utility model increases by two groups of (4) counterweight guide rail fixers at the stiff end support, increase by two groups of (4) counterweight guide rail movable locating devices at the movable end support, rotary main shaft at movable end installs a sprocket wheel additional, and the speed reduction gearing of motor, reductor, sprocket wheel, chain composition is installed at underframe.
The utility model has improved efficiency, improves the quality of product, has reduced labor strength.
Description of drawings
Fig. 1 is structural representation of the present utility model.
The specific embodiment
Referring to accompanying drawing, the lift standard knot is made frock, include underframe 1, underframe 1 one ends are rotatablely equipped with movable end support 2, the other end is equipped with stiff end support 3, be connected with connecting rod 5 between movable end support 2 and the stiff end support 3, four corners of movable end support 2 have screwed togather fastening screw 6 respectively, the outer end of fastening screw 6 is equipped with handwheel 7, on the stiff end support 3 of fastening screw 6 relative directions standard knot locating piece 8 is installed, fastening screw 6 slid underneath are provided with counterweight track movement registration arm 9, be set with spring 10 on the counterweight track movement registration arm 9, the stiff end support of counterweight track movement registration arm relative direction is provided with counterweight tracks positioned piece 4, underframe both sides part is connected with support bar, the movable end back-end support is connected with motor 11 by chain, and motor 11 is connected with reductor 12, and reductor and movable end support chain are in transmission connection.
