Description

Technical Field

[0001] The present invention relates to auxiliary equipment in a structural laboratory, and particularly to a structural test piece moving and installing device used in a structural laboratory. Background Art

[0002] A structural laboratory includes a reaction pedestal and a reaction wall arranged perpendicular to the reaction pedestal. A reaction frame is fixed on the reaction pedestal. When an earthquake resistance test needs to be carried out on a structural test piece such as a building wall, the building wall is moved to the lower side of the reaction frame. A vertical hydraulic cylinder for applying a vertical load to the upper end of the building wall is installed on the reaction frame. The vertical hydraulic cylinder is used to simulate the self-weight of the building above the building wall in a real earthquake environment. A horizontal actuator for applying a horizontal load to the building wall is arranged on the reaction wall, and the horizontal actuator simulates the horizontal force received by the building component in the earthquake environment.

[0003] In addition to building walls, other common structural test pieces also include beams, slabs, columns, beam-column joints, etc. These test pieces are mostly made of steel structures or reinforced concrete structures, and the size and self-weight of the test pieces are large. It is very difficult to move and install the test pieces to a specified position under the reaction frame.

[0018] For the convenience of understanding the present invention, the present invention will be described in more detail below with reference to the drawings and specific embodiments. The preferred embodiments of the present invention are shown in the drawings. However, the present invention can be implemented in many different forms and is not limited to the embodiments described in this specification. On the contrary, the purpose of providing these embodiments is to make the understanding of the disclosure content of the present invention more thorough and comprehensive.

[0019] It should be noted that unless otherwise defined, all technical and scientific terms used in this specification have the same meaning as commonly understood by those skilled in the technical field to which the present invention belongs. The terms used in the specification of the present invention are only for the purpose of describing specific embodiments and are not used to limit the present invention.

[0020] Embodiment 1 of a structural test piece transfer and installation device used in conjunction with a structural test laboratory in the present invention is as follows Figures 1 - 5 shown: It includes a set of mobile lifting units. This set of mobile lifting units includes two mobile lifting units 20 arranged at intervals left and right. The mobile lifting unit 20 includes a unit base 3 with traveling wheels 1 arranged at the bottom. The traveling wheels 1 are driven by a traveling wheel driving mechanism. Under the drive of the traveling wheel driving mechanism, the traveling wheels can turn and travel. The cooperation between the traveling wheel driving mechanism and the traveling wheels belongs to the prior art and will not be elaborated here. In this embodiment, four traveling wheels 1 are distributed at the four corners of the bottom of each unit base.

[0021] Four support legs 2 that can be telescoped up and down are arranged at the bottom of the unit base. The four support legs 2 are distributed at the four corners of the unit base. When the unit base needs to move, the four support legs retract. When the unit base does not move, the four support legs extend and contact the ground, which can ensure the stability of the unit base.

[0022] A vertical guiding structure is arranged on the unit base. A jacking support 8 is guided and movably assembled on the vertical guiding structure. A vertical loading cylinder 6 for driving the jacking support to move up and down is arranged between the unit base 3 and the jacking support 8. The vertical loading cylinder 6 is a hydraulic cylinder. A first cross beam 10 extending in the left - right direction is arranged between the jacking supports of the two mobile lifting units in the same set of mobile lifting units. An electric hoist 15 is guided and movably assembled along the left - right direction on the first cross beam 10. Item 19 in the figure represents the hoist traveling wheel for the cooperation between the electric hoist and the first cross beam; item 18 represents the hook of the electric hoist.

[0023] In this embodiment, the vertical guiding structure includes a left channel steel 5 and a right channel steel 4 with opposite - facing notches. The left channel steel 5 and the right channel steel 4 are arranged vertically. The outer sides of the left channel steel 5 and the right channel steel 4 are fixedly connected by two square fixing frames 7 arranged at intervals in the up - down direction. The inner cavities of the left channel steel and the right channel steel form a guiding channel 16 extending in the up - down direction. Diagonal braces 17 are arranged between the bottoms of the left channel steel and the right channel steel and the unit base.

[0024] The jacking support includes a support top plate 9. On the support top plate 9, a left guiding rod 21 that is in guiding sliding fit with the inner cavity of the left channel steel in the up - down direction and a right guiding rod 22 that is in guiding sliding fit with the inner cavity of the right channel steel in the up - down direction are fixed. The jacking support further includes a first frame rod 23 and a second frame rod 24 located on the front and rear sides of the left guiding rod, and the jacking support further includes a third frame rod 25 and a fourth frame rod 26 located on the front and rear sides of the right guiding rod. The first frame rod 23 and the third frame rod 25 are connected by two frame rod cross beams 27 arranged at intervals in the up - down direction. The second frame rod 24 and the fourth frame rod 26 are connected by two frame rod cross beams 27 arranged at intervals in the up - down direction.

[0025] The frame bar cross beams 27 at the lower position are connected by frame bar longitudinal beams 28, and the frame bar longitudinal beams are located between the left guide bar and the right guide bar. The lower ends of the left guide bar and the right guide bar are cantilever structures.

[0026] The bottom of the cylinder body of the vertical loading cylinder is fixed on the unit base, and the top of the piston rod of the vertical loading cylinder is connected to the top plate of the bracket.

[0027] A beam support 11 is fixed to the upper end of the bracket top plate, and a beam insertion hole for the end of the first beam 10 to be adapted and inserted is provided on the beam support 11.

[0028] When using Figure 1 As shown, for structural test pieces with smaller size and structure, only two mobile lifting units are needed to cooperate, the piston rod of the vertical loading cylinder is retracted, the height of the first crossbeam and the electric hoist is lowered, and then the hook of the electric hoist is lowered to lift the structural test piece, and then the piston rod of the vertical loading cylinder is extended to raise the height of the first crossbeam and the electric hoist, that is, to raise the height of the structural test piece, and the walking wheel driving mechanism drives the two mobile lifting units to move synchronously, so as to lift the structural test piece to the lower side of the reaction frame, and the supporting legs are extended to contact the ground, and the left and right position of the structural test piece is changed by the left and right movement of the electric hoist along the first crossbeam. After the left and right position of the structural test piece is adjusted to the right, the piston rod of the vertical loading cylinder is retracted, and the hook of the electric hoist is lowered to place the structural test piece on the ground of the reaction pedestal.

[0029] Embodiment 2 of a structural test piece transfer device for use in a structural test laboratory Figures 6 - 7 As shown: Embodiment 2 differs from Embodiment 1 in that, in this embodiment, the test component moving equipment is composed of two groups of mobile lifting units, and the adjacent lifting brackets of the two groups of mobile lifting units are detachably connected by a second cross beam 14. Specifically, a pin support 13 is provided on the top of the beam support for connecting to the end of the second cross beam through a pin.

[0030] Embodiment 2 can be used for lifting structural test pieces with larger size and heavier weight. When in use, the electric hoists 15 on the two first beams 10 lift the two ends of the structural test piece respectively. The setting of the second beam 14 is conducive to improving the overall stability of the structural test piece transfer equipment. The number of mobile lifting units can be selected according to the size and size of the structural test piece.

[0031] Embodiment 3 of a structural test piece transfer device for use in a structural test laboratory Figures 8 - 12 As shown: Example 3 is different from Example 2 in that, in Example 2, after the structural test piece moving equipment is moved into place, the left and right position of the structural test piece can only be moved and adjusted by moving the electric hoist along the first crossbeam. At this time, since the entire structural test piece moving equipment is composed of four mobile lifting units, its overall movement is not convenient, and the structural test piece cannot perform secondary adjustment of the position in the front and rear directions.

[0032] In Example 3, through the design of the corresponding structure, after the structural test piece moving equipment is moved to the lower side of the reaction frame and the supporting legs are extended to cooperate with the ground, the structural test piece can be moved and adjusted not only in the left and right directions, but also in the front and back directions.

[0033] Specifically, in this embodiment, a support guide groove 34 is provided at the top of the jacking bracket, and the guide direction extends along the front-back direction. The beam support 11 is guided and moved and assembled in the support guide groove 34. A support rack 36 arranged along the front-back direction is fixedly provided at the bottom of the support guide groove. A support drive motor 39 is provided on the beam support 11, and a drive gear 40 meshing with the support rack is connected on the motor shaft of the support drive motor 39. The support drive motor 39 rotates forward with the drive gear 40, and the drive gear 40 meshes with the support rack 36 for transmission, so that the beam support 11 can move forward with the first crossbeam 10 connected thereto; the support drive motor rotates reversely with the drive gear, and the drive gear 40 meshes with the support rack 36 for transmission, so that the beam support 11 can move backward with the first crossbeam 10 connected thereto.

[0034] In order to ensure the connection strength between the two groups of mobile lifting units and expand the front-to-back movement range of the beam support, in this embodiment, the two adjacent lifting brackets in the front-to-back direction are respectively referred to as the first lifting bracket and the second lifting bracket. The front end of the second crossbeam is fixed to the top of the first lifting bracket by bolts 29, and the rear end of the second crossbeam is fixed to the top of the second lifting bracket by bolts. The lifting bracket is provided with bolt holes 41 for the bolts 29 to pass through. The second crossbeam 14 includes a front crossbeam portion 31 located at the front side of the first lifting bracket, a rear crossbeam portion 33 located at the rear side of the second lifting bracket, and an intermediate crossbeam portion 32 located between the first lifting bracket and the second lifting bracket. The front crossbeam portion 31, the intermediate crossbeam portion 32, and the rear crossbeam portion 33 are provided with crossbeam racks 37 that are connected to the corresponding support racks 36 and crossbeam guide grooves 35 that are connected to the corresponding support guide grooves. A positioning hole 38 is provided on the top of the lifting bracket, and a positioning protrusion 30 for positioning and matching with the corresponding positioning hole is provided on the second crossbeam.

[0035] When the second crossbeam needs to be assembled, insert the positioning protrusion on the second crossbeam into the corresponding positioning hole of the grain support from top to bottom, and then fix the second crossbeam to the corresponding lifting bracket with bolts. The crossbeam rack and the support rack are butted. Driven by the support drive motor, the beam support can move back and forth between the support guide groove and the crossbeam guide groove. That is to say, the beam support can move from the support guide groove to the crossbeam guide groove, or from the crossbeam guide groove to the support guide groove. The setting of the second crossbeam not only ensures the connection strength between the two sets of moving lifting units, but also expands the front-back movement range of the beam support.

[0036] The first crossbeam and the second crossbeam are synchronously moved back and forth by four beam supports, so as to realize the secondary adjustment of the front-back position of the structural test piece.
