Description

Technical Field

[0001] The utility model belongs to the technical field of scaffolds, in particular to a scaffold which is easy to move and install. Background Art

[0002] Scaffolding is a working platform set up to ensure the smooth progress of each construction process. It is mainly used in building construction, bridge construction, stage construction and other fields, so that workers can carry out construction work at different heights. Scaffolding is usually composed of steel pipes, fasteners, scaffolding boards, etc. It has a certain stability and load-bearing capacity and can withstand the weight of workers, tools and building materials. It can provide construction workers with a safe and convenient operating space, which is convenient for wall construction, plastering, painting, equipment installation and other work. As the project progresses, the scaffolding can be moved and assembled as needed, so a movable small and medium-sized scaffolding is often used.

[0003] When installing the vertical poles for support, since the vertical poles are made of steel pipes, it is usually necessary to first fix or weld a connector at one end of the vertical pole with bolts, and then fix the connector to the top of the base plate with bolts so that the vertical pole is fixed to the top of the base plate. Therefore, multiple bolts are required when installing the vertical poles, which makes the installation of the vertical poles more troublesome and it is easy to miss the bolts when installing them, resulting in safety risks. Utility Model Content

[0004] The purpose of the utility model is to provide a scaffold that is easy to install and move, and solves the problem that the existing scaffold installation process is relatively complicated through the arrangement of a fixing component and a driving component.

[0005] In order to solve the above technical problems, the present invention is achieved through the following technical solutions:

[0006] The utility model is a scaffold that is easy to move and install, comprising a base plate, a support frame sleeved on the top of the base plate, a plurality of pulleys fixed to the bottom of the base plate, a plurality of fixing components fixed to the bottom of the base plate, a plurality of slide grooves penetrating the top of the base plate in a circular array, and guide rails fixed to the two inner sides relative to each other of the plurality of slide grooves.

[0007] The fixing assembly includes a mounting box fixed to the bottom of the base plate, a connecting frame slidingly engaged inside the mounting box, a first limiting rod slidingly engaged with the mounting box fixed to the bottom of the connecting frame, a second limiting rod slidingly engaged with the mounting box fixed to the top of the connecting frame, a first disc slidingly engaged inside the connecting frame, a sliding rod fixed to a position off-center of the first disc, a connecting column fixed to the top of the second limiting rod, a plurality of L-shaped plates fixed to the circumferential side of the connecting column in a circumferential array, and two steering columns fixed to one side of each of the L-shaped plates.

[0008] The sliding groove is fitted with a fixing member, and the fixing member includes a slide plate that slides on the guide rail. An arc-shaped card is fixed on the top of the slide plate, and a steering plate is fixed on the inner wall of the arc-shaped card plate. A steering groove is opened on one side of the steering plate, and the steering column slides with the steering groove.

[0009] The utility model is further configured such that a driving assembly is provided at one end of the first disc, the driving assembly includes a trapezoidal connecting rod that slides with the mounting box, a second disc is fixed at one end of the trapezoidal connecting rod, and a shift rod is fixed to the circumferential side of the second disc.

[0010] The utility model is further configured such that a sleeve is fixed to the other end of the trapezoidal connecting rod, the sleeve is slidably engaged with the slide rod, a clamping plate is fixed to the peripheral side of the slide rod, and a first clamping groove is provided on the inner peripheral side of the sleeve to slidably engage with the clamping plate.

[0011] The utility model is further configured as follows: two symmetrical clamping blocks are fixed on the circumferential side of the trapezoidal connecting rod, a guide column is fixed on an inner side of the mounting box, a trapezoidal hole is penetrated through one end of the guide column, a plurality of second clamping grooves are provided in a circular array on the inner circumferential side of the trapezoidal hole, and the second clamping grooves are slidably engaged with the clamping blocks.

[0012] The utility model is further configured such that the support frame includes vertical poles sleeved on the outer peripheral side of the arc-shaped card plate, a cross bar is fixedly connected between two adjacent vertical poles through fasteners, and pedals are commonly fixed on the two cross bars located at the top.

[0013] The utility model is further configured such that the side surfaces of the two horizontal bars at the bottom are fixedly connected to support rods through fasteners, one end of the support rods is fixed with a fixing plate, a fixing threaded rod is threadedly connected to the fixing plate, and a support plate is fixed to the bottom of the fixing threaded rod.

[0014] The utility model has the following beneficial effects:

[0015] 1. The utility model pulls the second disc so that the card block slides completely from the second card slot into the trapezoidal hole, and then the lever can be toggled to drive the second disc to rotate, and the second disc drives the trapezoidal connecting rod to rotate, and the trapezoidal connecting rod drives the sleeve to rotate, and the sleeve drives the first disc to rotate through the sliding rod, and the first disc drives the connecting frame to move upward, and the connecting frame drives the connecting column to move through the second limiting rod, so that the steering column slides in the steering groove, and the various fixing parts in the vertical pole cavity begin to move away from each other until the outer peripheral side surface of the arc-shaped card plate is tightly fitted with the inner peripheral side surface of the vertical pole, and the friction generated by the two fitting surfaces is used to fix the vertical pole on the outer peripheral side surface of the arc-shaped card plate, so as to achieve rapid fixation of the vertical pole.

[0016] 2. The utility model prevents the sleeve from rotating by clamping the clamping block in the two second clamping grooves. Since the clamping plate is clamped in the first clamping groove, the sliding rod in the sleeve is also unable to rotate. The first disc remains stationary, so that the outer peripheral side of the arc-shaped clamping plate is kept in contact with the inner peripheral side of the vertical pole, thereby ensuring the stability of the vertical pole. At the same time, by clamping the clamping block in different second clamping grooves, the fixing assembly can be applied to vertical poles of different sizes.

[0017] Of course, any product implementing the present invention does not necessarily need to achieve all of the advantages described above at the same time. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0030] The following will be combined with the accompanying drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention. Specific embodiment 1

[0032] See also Figure 1-9 The utility model is a scaffold that is easy to move and install, including a base plate 1, a support frame 5 is sleeved on the top of the base plate 1, a number of pulleys 6 are fixed to the bottom of the base plate 1, a number of fixing components 2 are fixed to the bottom of the base plate 1, a number of slide grooves 101 are opened in a circular array on the top of the base plate 1, and guide rails 102 are fixed to the two inner sides of the plurality of slide grooves 101. The fixing component 2 includes a mounting box 201 fixed to the bottom of the base plate 1, a connecting frame 202 is slidably matched inside the mounting box 201, a first limiting rod 203 that is slidably matched with the mounting box 201 is fixed to the bottom of the connecting frame 202, and a second limiting rod 203 that is slidably matched with the mounting box 201 is fixed to the top of the connecting frame 202. 04, a first disc 205 is slidably fitted in the connecting frame 202, a sliding rod 206 is fixed to the first disc 205 at a position offset from the center, a connecting column 207 is fixed to the top of the second limiting rod 204, a plurality of L-shaped plates 208 are fixed in a circular array on the side surface of the connecting column 207, two steering columns 209 are fixed on one side of the plurality of L-shaped plates 208, a fixing member 3 is slidably fitted in the slide groove 101, the fixing member 3 includes a slide plate 301 slidably fitted on the guide rail 102, an arc-shaped card plate 302 is fixed on the top of the slide plate 301, a steering plate 303 is fixed to the inner wall of the arc-shaped card plate 302, a steering groove 304 is penetrated on one side of the steering plate 303, and the steering column 209 slidably fits with the steering groove 304.

[0033] Specifically, the support frame 5 includes a vertical rod 501 that is sleeved on the outer peripheral side of the arc-shaped clamping plate 302.

[0034] The operation process of this embodiment is as follows: by driving the first disc 205 to rotate clockwise or counterclockwise around the sliding rod 206 fixed at its off-center position, the first disc 205 drives the connecting frame 202 to move upward or downward, and the first limiting rod 203 and the second limiting rod 204 are used to constrain the connecting frame 202 to move linearly. When installing the support frame 5, the vertical rod 501 is first sleeved on the arc-shaped clamping plate 302, and then the first disc 205 is driven to rotate to drive the connecting frame 202 to move upward. The connecting frame 202 drives the connecting column 207 to move upward through the second limiting rod 204, and the L-shaped plate 208 on the side surface of the connecting column 207 moves synchronously, so that the steering column 209 slides in the steering groove 304. Since the slide plate 301 is slidably fitted on the guide rail 102, the fixing part 3 cannot move upward, so that when the steering column 209 slides in the steering groove 304, it will drive the fixing part 3 to move along the guide rail 102, and the various fixing parts 3 in the cavity of the vertical rod 501 begin to move away from each other until the outer peripheral side surface of the arc-shaped clamping plate 302 is tightly fitted with the inner peripheral side surface of the vertical rod 501, and the friction generated by the two fitting surfaces is used to fix the vertical rod 501 on the outer peripheral side surface of the arc-shaped clamping plate 302. When the vertical rod 501 needs to be disassembled, the first disc 205 is rotated in the opposite direction to move the connecting frame 202 downward, and the fixing part 3 is moved in the opposite direction, so that the arc-shaped clamping plate 302 is away from the vertical rod 501, and the vertical rod 501 can be pulled out from the arc-shaped clamping plate 302. Specific embodiment 2

[0036] See also Figure 1-9 On the basis of the specific embodiment 1, specifically, a driving assembly 4 is provided at one end of the first disc 205, and the driving assembly 4 includes a trapezoidal connecting rod 401 that slides with the installation box 201, and a second disc 402 is fixed to one end of the trapezoidal connecting rod 401, and a shift rod 403 is fixed to the side surface of the second disc 402, and a sleeve 404 is fixed to the other end of the trapezoidal connecting rod 401. The sleeve 404 slides with the slide rod 206, and a clamping plate 210 is fixed to the side surface of the slide rod 206. The inner side surface of the sleeve 404 is provided with a first clamping groove 405 that slides with the clamping plate 210, and two symmetrical clamping blocks 406 are fixed to the side surface of the trapezoidal connecting rod 401. A guide column 211 is fixed to an inner side surface of the installation box 201, and a trapezoidal hole 212 is opened at one end of the guide column 211, and a plurality of second clamping grooves 213 are opened in a circular array on the inner side surface of the trapezoidal hole 212. The second clamping groove 213 slides with the clamping block 406.

[0037] The operation process of this embodiment is as follows: when there is no need to rotate the first disc 205, the two clamping blocks 406 on the side surfaces of the trapezoidal connecting rod 401 are respectively clamped in the two second clamping grooves 213, so that the sleeve 404 cannot rotate. Since the clamping plate 210 is clamped in the first clamping groove 405, the sliding rod 206 in the sleeve 404 is also unable to rotate, and the first disc 205 remains stationary, so that the outer peripheral side surface of the arc clamping plate 302 is kept in contact with the inner peripheral side surface of the vertical rod 501, thereby ensuring the stability of the vertical rod 501. When it is necessary to rotate the first disc 205, the second disc 402 is pulled in the direction away from the installation box 201, and the second disc 402 drives the trapezoidal connecting rod 40 1 is moved so that the clamping block 406 slides completely from the second clamping groove 213 into the trapezoidal hole 212. At this time, the lever 403 can be toggled to drive the second disc 402 to rotate. The second disc 402 drives the trapezoidal connecting rod 401 to rotate. The trapezoidal connecting rod 401 drives the sleeve 404 to rotate. The sleeve 404 drives the first disc 205 to rotate through the sliding rod 206, so that the multiple fixing members 3 in the cavity of the vertical pole 501 begin to move away from or approach each other, thereby achieving the fixation or removal of the vertical pole 501. At the same time, the clamping block 406 is clamped into different second clamping grooves 213 to correspond to vertical poles 501 of different sizes and specifications, so as to facilitate the replacement of vertical poles 501 with different load-bearing capacities. Specific embodiment three

[0040] The operating process of this embodiment is as follows: after the support frame 5 is installed on the top of the base plate 1 and the scaffold is moved to the working position, the fixed threaded rod 506 is rotated so that the fixed threaded rod 506 moves downward relative to the fixed plate 505 until the support plate 507 fixed at the bottom of the fixed threaded rod 506 is pressed against the ground, and the fixed plate 505 is fixedly connected to the cross bar 502 through the support rod 504, so that the scaffold is fixed to the ground.
