Description

Technical Field

[0001] This utility model relates to the field of weighing technology, specifically to an adjustable weighing support device for an elevator. Background Technology

[0002] Construction elevators are commonly referred to as construction hoists, but the definition of a construction hoist is broader, including construction platforms. A typical construction elevator consists of several parts, including a car, drive mechanism, standard sections, wall attachments, chassis, railings, and electrical system. It is a frequently used construction machine for carrying personnel and materials. Workers often rely on intuition to load materials into the basket. To accurately determine the weight of the materials in the basket, a weighing device is used. This weighing device requires a supporting structure. A search revealed existing technology (publication number: CN202420769044.X) for an adjustable construction hoist. The text describes a weighing support device, stating that "through the design of limiting plates, a drive mechanism, and clamping plates, the cooperation of two limiting plates limits the front and rear sides, and the movement of the two clamping plates in opposite directions clamps and fixes the left and right sides of the base, achieving the purpose of quickly fixing the base and facilitating material weighing; through the design of clamping plates, screws, abutting plates, and handwheels, the handwheel rotates the screw to move the abutting plate, which abuts against the 'first fixed rod,' further improving the stability of the device." However, in the existing technology, the limiting distance between the front and rear limiting plates of the base is narrow and difficult to adjust effectively, resulting in a limited range of weighable materials supported by the lifting mechanism. Utility Model Content

[0003] To overcome the shortcomings of existing technologies, an adjustable weighing support device for a lifting platform is provided to solve the problem that the narrow limiting distance between the front and rear limiting plates of the base makes it difficult to adjust effectively, resulting in a limited range of weighing materials that can be supported by the lifting platform.

[0004] To achieve the above objectives, an adjustable weighing support device for an elevator is provided, comprising: a support platform and a support base, wherein the support base is welded to the lower end face of the support platform.

[0005] The support platform has a first clamping plate, a second clamping plate, a third clamping plate, and a fourth clamping plate arranged in a circular array on its surface. An extension frame is welded to the outer end of the support base. A fixed cover plate is connected to the side end of the extension frame by fastening bolts. An adjusting screw is installed on the inner side of the extension frame. The surface of the adjusting screw is connected to the first clamping plate, the second clamping plate, the third clamping plate, and the fourth clamping plate respectively through a driving block. An auxiliary telescopic plate is movably inserted into the upper surface of the support platform.

[0006] Furthermore, the lower end faces of the first, second, third, and fourth clamping plates are screwed with driving blocks; and the lower ends of the first, second, third, and fourth clamping plates are each provided with adjusting screws.

[0007] Furthermore, rubber pads are glued to the sides of the first, second, third, and fourth clamping plates, and the first, second, third, and fourth clamping plates are trapezoidal in shape, narrower at the top and wider at the bottom.

[0008] Furthermore, a limiting groove is provided on the upper surface of the support platform; and an auxiliary telescopic plate is inserted into the limiting groove for limiting; and a positioning stud is screwed onto the lower surface of the support platform.

[0009] Furthermore, the lower surface of the auxiliary telescopic plate is provided with a positioning slot; and the positioning stud is inserted into the positioning slot, and the side end of the auxiliary telescopic plate contacts the outer side of the support plate through an arc-shaped block.

[0010] Furthermore, a transmission column is installed in the middle of the inner side of the support base; and adjusting screws are connected to both the front and rear ends of the transmission column.

[0011] Furthermore, an adjusting pin is provided on the outer end face of the fixed cover plate; and the side end of the adjusting pin is connected to the adjusting screw.

[0012] The beneficial effects of this utility model are as follows: the adjustable weighing support device of the elevator utilizes the rotational movement of the adjusting screw inside the support base frame to drive the four sets of clamping plates distributed in the front, back, left, and right of the support plate to move horizontally. This allows the four sets of clamping plates to support and clamp the material to be weighed in a more centered position, which facilitates the expansion of the support area of ​​the weighing support device used in the elevator, and allows for more flexible adjustment and support of weighing materials of different sizes. It also facilitates the centered support of the weighing support device, enhances the support stability of the weighing support device, reduces the weighing error caused by the material deviating from the center, ensures the accuracy of material weighing, and improves the support effect of the weighing support device of the elevator.

[0019] Reference Figures 1 to 5 As shown, this utility model provides an adjustable weighing support device for a lift, including: a support platform 1 with a first clamping plate 2, a second clamping plate 21, a third clamping plate 22 and a fourth clamping plate 23 arranged in a ring array on the upper surface; an extension frame 52 welded to the outer end of the support base 5; a fixed cover plate 51 connected to the side end of the extension frame 52 by fastening bolts 54; an adjusting screw 3 installed on the inner side of the extension frame 52; the surface of the adjusting screw 3 connected to the first clamping plate 2, the second clamping plate 21, the third clamping plate 22 and the fourth clamping plate 23 respectively by a driving block 31; and an auxiliary telescopic plate 4 movably inserted into the upper surface of the support platform 1.

[0020] First, place the weighing support device at the weighing device of the elevator. Then, place the material to be weighed on the upper surface of the support platform 1. When the material exceeds the surface of the support platform 1, the auxiliary telescopic plate 4 can be pulled outward to support the material exceeding the surface of the support platform 1. The positioning stud 11 is used to insert and position the auxiliary telescopic plate 4. Then, rotate the adjusting screw head 32 on the side of the adjusting screw 3 at the lower end of the first clamping plate 2 to make the adjusting screws 3 at the lower ends of the first clamping plate 2 and the third clamping plate 22 rotate synchronously. This causes the driving block 31 to drive the first clamping plate 2 and the third clamping plate 22 to move synchronously in opposite directions until the first clamping plate 2 and the third clamping plate 22 move synchronously in opposite directions. The third clamping plate 22 clamps and adheres to the front and rear sides of the material on the support platform 1. Then, observe the position of the material on the left and right scale lines on the support platform 1, and rotate the adjusting screws 3 at the lower end of the second clamping plate 21 and the fourth clamping plate 23 in sequence to make the second clamping plate 21 and the fourth clamping plate 23 clamp the material on the left and right sides in a relatively symmetrical manner. This ensures that the material to be weighed is located in the center position of the support platform 1, and the weight value of the material can be obtained through the weighing device. This effectively reduces the weighing error caused by the material deviating from the center, ensures the accuracy of material weighing, and improves the support stability and adjustment effect of the weighing support device of the elevator.

[0021] In this embodiment, a driving block 31 is screwed to the lower end face of the first clamping plate 2, the second clamping plate 21, the third clamping plate 22, and the fourth clamping plate 23; and an adjusting screw 3 is correspondingly provided at the lower end of each of the first clamping plate 2, the second clamping plate 21, the third clamping plate 22, and the fourth clamping plate 23. Rubber pads 24 are glued to the sides of the first clamping plate 2, the second clamping plate 21, the third clamping plate 22, and the fourth clamping plate 23 are trapezoidal in shape, narrower at the top and wider at the bottom.

[0022] In a preferred embodiment, the first clamping plate 2, the second clamping plate 21, the third clamping plate 22, and the fourth clamping plate 23 are located at the front, left, rear, and right sides, respectively, to achieve multi-directional clamping of the material on the support platform 1 and prevent the material from moving on the support platform 1 and affecting normal weighing. The first clamping plate 2 and the third clamping plate 22 are synchronously driven, which facilitates the synchronous reverse movement of the first clamping plate 2 and the third clamping plate 22 to clamp the material in a centered position, ensuring that the material being weighed on the support platform 1 is at the center of the weighing support, effectively reducing the weighing error caused by the material deviating from the center, and ensuring the accuracy of the material weighing. The drive block 31 converts the rotational motion of the adjusting screw 3 into linear motion, thereby driving the first clamping plate 2, the second clamping plate 21, the third clamping plate 22, and the fourth clamping plate 23 to move horizontally, so that the clamps on the support platform 1 can support and clamp materials of different sizes.

[0023] In this embodiment, a limiting groove 12 is formed on the upper surface of the support plate 1; and an auxiliary telescopic plate 4 is inserted into the limiting groove 12 for limiting. A positioning stud 11 is screwed onto the lower surface of the support plate 1. A positioning slot 42 is formed on the lower surface of the auxiliary telescopic plate 4; and the positioning stud 11 is inserted into the positioning slot 42. The side end of the auxiliary telescopic plate 4 contacts the outer surface of the support plate 1 through an arc-shaped block 41.

[0024] In a preferred embodiment, by pulling the arc-shaped block 41, the auxiliary telescopic plate 4 is moved within the limiting groove 12, allowing the auxiliary telescopic plate 4 to extend or retract into the support platform 1, thus providing auxiliary support for materials extending beyond the surface of the support platform 1. The positioning stud 11 is screwed into the positioning slot 42 of the auxiliary telescopic plate 4 to facilitate limiting the position of the auxiliary telescopic plate 4.

[0025] In this embodiment, a transmission column 53 is installed in the middle of the inner side of the support base 5; and adjusting screws 3 are connected to both the front and rear ends of the transmission column 53. An adjusting head 32 is provided on the outer end face of the fixed cover plate 51; and the side end of the adjusting head 32 is connected to the adjusting screw 3.

[0026] In a preferred embodiment, the transmission column 53 is used to connect the adjusting screws 3 at the lower ends of the first clamping plate 2 and the third clamping plate 22. The threads on the surfaces of the adjusting screws 3 at the lower ends of the first clamping plate 2 and the third clamping plate 22 are opposite, so that the adjusting column head 32 drives the adjusting screws 3 at the lower ends of the first clamping plate 2, the second clamping plate 21, the third clamping plate 22 and the fourth clamping plate 23 to rotate. This achieves the effect of adjusting the lateral support and clamping position of the first clamping plate 2, the second clamping plate 21, the third clamping plate 22 and the fourth clamping plate 23, which facilitates the expansion of the support area of ​​the weighing support device used in the elevator and allows for more flexible adjustment and support of weighing materials of different sizes.

[0027] This utility model's adjustable weighing support device for a lifting platform effectively solves the problem in existing technologies where the narrow spacing between the front and rear limiting plates of the base makes effective adjustment difficult, resulting in a limited range of materials that can be weighed with the lifting platform's auxiliary support. It facilitates expanding the support area of ​​the weighing support device used in the lifting platform, allowing for more flexible adjustment and support of materials of different sizes. It also ensures that the weighing support device is centered on the material, enhancing its support stability, reducing weighing errors caused by the material deviating from the center, ensuring accurate weighing, and improving the support effect of the lifting platform's weighing support device. This invention is suitable for adjustable weighing support devices for lifting platforms.
