Description
Technical Field
The utility model relates to a case roof beam prestressing force jack installation device.
Background
In the case roof beam prestressing force stretch-draw in-process, we often adopt simple and easy tripod and electric block to install as hoist system to the jack, when the jack installation, safety protection resets the baffle, but long-term practice discovers, when adopting this kind of mode to install the jack, though to promoting simply down on the jack, nevertheless around the jack, about the mounted position adjustment operation very loaded down with trivial details, the interim safety protection of adjustment process needs dismouting repeatedly moreover, wastes time and energy.
SUMMERY OF THE UTILITY MODEL
The utility model provides an above-mentioned not enough of technique provides an efficiency and the security of simple structure, convenient operation, improvement jack in the installation to improve a case roof beam prestressing force stretch-draw process efficiency's a case roof beam prestressing force jack installation device.
The utility model provides a case roof beam prestressing force jack installation device, includes the support frame that comprises top quadrilateral frame and four stands of support in the frame below, the top of frame all is equipped with the track on two edges of its symmetry, installs the slide with track roll connection between two tracks, the hanger rail that slide length direction was equipped with is followed to the bottom of slide, and the one end roll connection of rings is in the hanger rail, install the electric block who is used for hoist and mount jack on the other end of rings.
Furthermore, at least one side of the support frame is provided with a protective steel plate for sealing the side.
Furthermore, an oblique steel bar for reinforcing the connection strength of the frame and the upright post is arranged between the frame and the upright post.
Furthermore, the bottom of the upright post is provided with a universal caster wheel with a brake. The support frame is formed by splicing channel steel.
Adopt above-mentioned structure, the X axial displacement of electric block is realized through the displacement means that the frame top surface set up to this device, and Y axial displacement through hanger rail realization electric block on the slide, the vertical direction removal of the jack of electron is realized through electric block, and the universal castor of stand bottom installation can realize this device and portably remove between different case roof beams, and the protection steel sheet of framework installation plays safety protection's effect in jack stretch-draw process, improves the security of device.
In conclusion, the device is simple in structure and convenient to operate, and improves the efficiency and the safety of the jack in the installation process, so that the efficiency of the box girder prestress tensioning process is improved.

Detailed Description
The following describes a specific embodiment of the present invention with reference to the drawings.
As shown in figure 1, a box girder prestress jack mounting device comprises a support frame 1 consisting of a top quadrilateral frame and four upright posts supported below the frame, wherein two symmetrical edges of the top of the frame are provided with rails, a sliding plate 2 is mounted between the two rails, the sliding plate 2 is mounted on the rails through pulleys at the bottom of the sliding plate 2, the bottom of the sliding plate 2 is provided with a hanging rail along the length direction of the sliding plate 2, an electric hoist 3 is mounted in the hanging rail through a hanging ring, one end of the hanging ring is provided with a pulley mounted in the hanging rail, the other end of the hanging ring is provided with an electric hoist 3 for hoisting a jack 6, at least one side of the support frame 1 is provided with a protective steel plate 4 for sealing the side, oblique steel bars for enhancing the connection strength of the frame and the upright posts are arranged between the frame and the upright posts, and universal caster wheels 5 with brakes are mounted at the bottoms of, the support frame 1 is formed by splicing channel steel.
The preparation method comprises the following steps:
1. the height of the support frame 1 of the device is determined according to construction drawings, and in the embodiment, the height of the manufactured support frame 1 is about 60-80 cm higher than the height of the end of the box girder.
2. And (3) channel steel blanking, particularly, the top of the frame is used as a sliding track part and the bottom of the sliding plate 2 is used as a hanging rail part, welding seams need to be polished smoothly, and the width of the track is about 1cm wider than that of a pulley on the sliding plate 2.
3. The front protection steel plate 4 of the jack is arranged on the inner side of the support frame 1, and the steel plate is directly connected with the channel steel of the support frame 1 in a welding mode.
4. The lifting capacity of the electric hoist 3 and the load capacity of the universal caster 5 with the brake are matched according to the weight of the jack, so that the using capacity is met.
5. After the product is manufactured, the product can be used after being qualified by field experience debugging and acceptance.
The above-mentioned embodiments are only described for the preferred embodiments of the present invention, and are not intended to limit the concept and scope of the present invention, and various modifications and improvements made by the technical solutions of the present invention by those skilled in the art should fall into the protection scope of the present invention without departing from the design concept of the present invention, and the technical contents claimed by the present invention are all described in the claims.
