Description

Technical Field

[0001] This utility model relates to the field of concrete slab transfer technology, specifically to a transfer frame for transferring concrete slabs. Background Technology

[0002] Concrete slabs are panels used in construction projects. They are manufactured in factories and then transported to construction sites for installation. With the development of modern buildings towards high-rise and high-efficiency construction, the use of concrete slabs is increasing, and construction progress is significantly improved.

[0003] During the use of transfer frames for transporting concrete slabs, the concrete slabs are generally quite heavy. If they are handled and unloaded manually, it will seriously affect the construction progress and will also consume a lot of physical strength for the construction workers. In addition, due to manual handling, there is also a risk that the slabs will fall during transportation.

[0004] Therefore, we propose a transfer frame for transporting concrete slabs. Utility Model Content

[0005] The purpose of this invention is to provide a transfer frame for transporting concrete slabs, so as to solve the problems of freeing up manpower during transportation and reducing damage to concrete during transportation.

[0006] This utility model provides the following technical solution: a transfer frame for transferring concrete slabs, comprising two support plates arranged symmetrically in the transverse direction, with a main frame fixedly connected to both ends of the two support plates, two force-bearing frames fixedly connected between the two main frames, and a fixed seat fixedly connected between the two force-bearing frames, a driving assembly provided on the upper surface of the support plate, upper mounting seats fixedly connected to both sides of the lower end surface of the force-bearing frames, a connecting rod rotatably connected inside the upper mounting seat, a fixing clamp fixedly connected to the bottom end of the connecting rod, and a limiting assembly provided between the fixing clamp and the support plate.

[0007] The above components achieve the following effects: the support plate and the main frame and load-bearing frame are rigidly connected to form a stable rigid frame; the drive component provides a vertical movement path, driving the coordinated movement of the connecting rod and the fixing clamp, realizing the rapid clamping and release of the concrete slab; the limit component forms a positioning constraint; the rotatable connecting rod enables the fixing clamp to have a multi-angle adjustment function; and the linkage between the fixing clamp and the limit component realizes the automatic centering and clamping of the slab.

[0008] As a preferred embodiment of the above technical solution, the drive assembly includes a motor fixed to the upper surface of the fixed base and a lifting housing fixed to the upper surface of the fixed base. The output end of the motor is rotatably connected to the lifting housing. A suitable lead screw is provided on the lifting housing. A crossbar is fixedly connected to the bottom end of the lead screw. Limiting frames are fixedly connected to both ends of the crossbar. A limiting post is fixedly connected to the middle side wall of the connecting rod. The limiting post slides within the slot of the limiting frame.

[0009] The above components achieve the following effects: the motor acts as a power source, providing power to the elevator car body, driving the lead screw and crossbar to move vertically up and down, and the sliding cooperation between the limit frame and the limit column causes the connecting rod to move along a predetermined trajectory.

[0010] As a preferred embodiment of the above technical solution, the limiting component includes a limiting sleeve, a limiting block is fixed to one side of the lower end face of the limiting sleeve, and the limiting block is fixedly connected to the support plate. An inner sliding rod is sleeved and connected inside the limiting sleeve. One end of the inner sliding rod is rotatably connected to an upper connecting seat. The end of the upper connecting seat away from the inner sliding rod is fixed to the side wall of the fixing clamp. Sliding columns are symmetrically fixed to the outer side wall of the inner sliding rod. Sliding grooves are symmetrically opened on the outer side wall of the limiting sleeve. The sliding columns are slidably connected to the sliding grooves. A lower connecting seat is rotatably connected to the end of the limiting sleeve near the support plate, and the lower connecting seat is fixedly connected to the support plate.

[0011] The aforementioned components achieve the following effects: the limiting assembly achieves a stable guiding function through the connection structure between the limiting sleeve and the inner sliding rod; the use of the limiting block restricts the rotation range of the limiting assembly; and the guiding cooperation between the sliding column and the slide groove forms a positioning constraint.

[0012] The limit block restricts the guiding function of the limit component.

[0013] As a preferred embodiment of the above technical solution, omnidirectional wheels are fixedly connected to the bottom ends of both main frames.

[0014] The aforementioned components achieve the following effects: improved operational and mobility efficiency, and enhanced equipment adaptability.

[0015] As a preferred embodiment of the above technical solution, the fixed base is provided with a through hole for the lead screw to pass through.

[0016] The aforementioned components achieve the following effect: they enable the lead screw to pass securely through the fixed seat, thus ensuring the stability of the elevator car body and the lead screw during operation.

[0017] As a preferred embodiment of the above technical solution, the inner bottom wall of the fixing clamp is an inclined surface, and the inner bottom walls of both fixing clamps are inclined towards the center.

[0018] The effect achieved by the above components is to guide the clamped object to quickly center itself through the inclined guide structure.

[0019] Compared with the prior art, the beneficial effects of this utility model are:

[0020] In this utility model, a rigid frame composed of a support plate and a main frame is used as the load-bearing foundation. In conjunction with the motor-driven screw lifting mechanism and the limit frame guide structure in the drive assembly, the connecting rod can be precisely controlled to drive the fixed clamp to complete the vertical lifting and clamping action, ensuring the stability of concrete slab extraction. The limit assembly effectively prevents clamping deviation through the nested structure of the sleeve and the inner sliding rod and the axial constraint of the sliding column groove. At the same time, the inclined surface design of the inner bottom wall of the fixed clamp forms a self-centering guide, improving clamping efficiency and centering. The configuration of the bottom universal wheels enhances the mobility of the equipment. Attached Figure Description

Detailed Implementation

[0027] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0028] like Figures 1-5As shown, this utility model provides a technical solution: a transfer frame for transferring concrete slabs, comprising two support plates 103 arranged symmetrically in the horizontal direction, with a main frame 1 fixedly connected to both ends of the two support plates 103, two force-bearing frames 101 fixedly connected between the two main frames 1, and a fixed seat 104 fixedly connected between the two force-bearing frames 101, a driving component 2 provided on the upper end surface of the support plate 103, and upper mounting seats 304 fixedly connected to both sides of the lower end surface of the force-bearing frames 101, a connecting rod 301 rotatably connected inside the upper mounting seat 304, a fixing clamp 3 fixedly connected to the bottom end of the connecting rod 301, and a limiting component 30 provided between the fixing clamp 3 and the support plate 103.

[0029] In practical use, two horizontally symmetrical support plates 103 are fixed between the main frame 1, and two load-bearing frames 101 are fixedly connected between the two main frames 1 to form a stable frame structure. The two load-bearing frames 101 are fixedly connected to the fixing seat 104 to provide an installation position for the drive component 2. The connecting rod 301 in the mounting seat 304 on both sides of the lower end face of the load-bearing frame 101 drives the fixing clamp 3 to move to both sides of the plate, so that the fixing clamp 3 can clamp the concrete plate. A limiting component 30 is provided between the fixing clamp 3 and the support plate 103 to ensure that the clamping is firm.

[0030] As one implementation method in this embodiment, such as Figure 1 Figure 2 and Figure 4 As shown, the drive assembly 2 includes a motor 203 fixed to the upper surface of the fixed base 104 and a lifting platform housing 202 fixed to the upper surface of the fixed base 104. The output end of the motor 203 is rotatably connected to the lifting platform housing 202. A matching lead screw 201 is provided on the lifting platform housing 202. A crossbar 309 is fixedly connected to the bottom end of the lead screw 201. Limiting frames 303 are fixedly connected to both ends of the crossbar 309. A limiting post 302 is fixedly connected to the middle side wall of the connecting rod 301. The limiting post 302 slides in the slot 305 of the limiting frame 303.

[0031] In practical use, the drive assembly 2 drives the lifting platform housing 202 via the motor 203, which in turn drives the internal lead screw 201 to move up and down. The bottom of the lead screw 201 is fixedly connected to the crossbar 309. The bottom end of the crossbar 309 synchronously drives the connecting rod 301. The limiting post 302, fixed in the middle section of the connecting rod 301, slides along the slot 305 of the limiting frame 303, allowing the connecting rod 301 to generate compound motion. The slot 305 enables lifting and translation movements.

[0032] As one implementation method in this embodiment, such as Figure 5As shown, the limiting component 30 includes a limiting sleeve 3073. A limiting block 307 is fixed to one side of the lower end face of the limiting sleeve 3073, and the limiting block 307 is fixedly connected to the support plate 103. An inner sliding rod 3072 is slidably connected inside the limiting sleeve 3073. An upper connecting seat 3071 is rotatably connected to one end of the inner sliding rod 3072. The end of the upper connecting seat 3071 away from the inner sliding rod 3072 is fixed to the side wall of the fixing clamp 3. Sliding columns 3075 are symmetrically fixed to the outer side wall of the inner sliding rod 3072. Sliding grooves 3076 are symmetrically opened on the outer side wall of the limiting sleeve 3073. The sliding columns 3075 are slidably connected to the sliding grooves 3076. A lower connecting seat 3074 is rotatably connected to one end of the limiting sleeve 3073 near the support plate 103, and the lower connecting seat 3074 is fixedly connected to the support plate 103.

[0033] In practical use, the limiting block 307 is fixedly connected to the support plate 103, which plays a supporting and limiting role for the limiting sleeve 3073. The limiting sleeve 3073 is slidably connected to the inner sliding rod 3072, forming a stable linear guide. The limiting constraint of the sliding column 3075 and the sliding groove 3076 ensures the stability of the fixed clamp 3 during movement. At the same time, it is convenient for the operator to intuitively judge the working position of the fixed clamp 3. Meanwhile, its self-limiting characteristic can accurately control the maximum opening and closing angle.

[0034] As one implementation method in this embodiment, such as Figure 1 As shown, the bottom ends of both main frames 1 are fixedly connected to casters 102.

[0035] In actual use, the bottom ends of the two main frames 1 are fixedly connected with casters 102, which can enable normal passage in narrow and complex terrain.

[0036] As one implementation method in this embodiment, such as Figure 2 As shown, the fixed base 104 has a through hole 105 for the lead screw 201 to pass through.

[0037] In practical use, the fixed base 104 is provided with a through hole 105 for the lead screw 201 to pass through, ensuring that the lead screw 201 can pass through the fixed base 104 and connect with the crossbar 309. At the same time, the lead screw 201 can always maintain axial accuracy during rotation or lifting.

[0038] As one implementation method in this embodiment, such as Figure 1 As shown, the inner bottom wall of the fixing clamp 3 is an inclined surface, and the inner bottom walls of both fixing clamps 3 are inclined towards the middle.

[0039] In actual use, the inner bottom wall of the fixing clamp 3 is inclined, which can better fit the surface of the object being clamped during the clamping stage.

[0040] Working principle: The drive assembly motor 203 is started, driving the lifting platform housing 202 to rotate, which in turn drives the internal lead screw 201 to move vertically. A crossbar 309 is fixedly connected to the bottom of the lead screw 201, and the crossbar 309 synchronously drives the two end limit frames 303 to move. At this time, the limit post 302 in the middle section of the connecting rod 301 slides along the slot 305 of the limit frame 303. When the limit post 302 is at the top of the slot 305, the connecting rod 301 is in a vertical state, causing the fixing clamp 3 to be at its maximum opening. As the lead screw 201 descends, the limit... The column 302 slides along the path of the groove 305, forcing the connecting rod 301 to deflect around the upper mounting base 304, which drives the bottom fixing clamp 3 to retract inward to form a clamping action. During the clamping process, the limiting component 30 forms a linear guide through the sliding cooperation between the inner sliding rod 3072 and the limiting sleeve 3073. The sliding column 3075 precisely constrains the movement direction of the fixing clamp 3 along the displacement trajectory of the sliding groove 3076. At the same time, the fixed connection between the limiting block 307 and the lower connecting base 3074 ensures that the entire clamping system maintains axial stability.

[0041] The above embodiments are only used to illustrate the technical solution of this utility model, and are not intended to limit it.
