Description

Technical Field

[0001] The utility model relates to the technical field of suspension baskets, and more specifically, to a counterweight-free suspension basket rear support device and a suspension basket. Background Art

[0002] With the continuous development of construction technology, the building appearance has become increasingly rich, and special-shaped curtain walls are more and more used in building facades and roofs. In order to create a highly personalized building space and landscape, roof truss beams are widely used in building roofs. At present, curtain wall construction mostly uses suspension baskets as construction measures.

[0003] When installing the existing suspension basket, the following problems are likely to be faced:

[0004] First, the distance between the roof truss beam and the roof is too large, and the traditional rear support of the suspension basket is too short. Forcibly lengthening the rear support of the suspension basket is likely to cause the suspension basket to swing left and right during use, making it prone to instability.

[0005] Second, curtain wall construction and roof waterproof construction are carried out simultaneously, so the on-site installation of the suspension basket must wait until the roof waterproof construction is completed, which affects the overall project duration.

[0006] Third, the counterweight placed on the rear support is limited, resulting in a limited lifting weight and reduced work efficiency. Content of the Utility Model

[0007] The technical problem to be solved by the utility model is to provide a counterweight-free suspension basket rear support device and a suspension basket.

[0008] The solution adopted by the utility model to solve the technical problem is:

[0009] A counterweight-free suspension basket rear support device is sleeved on the outside of the truss beam; it includes a U-shaped frame provided with an installation cavity, two groups of clamping members symmetrically arranged inside the U-shaped frame, and a limiting rod connected to the U-shaped frame and cooperating with the clamping members and the U-shaped frame to form a clamping cavity; the truss beam is located in the clamping cavity.

[0010] In some possible implementation manners, the clamping member includes a telescopic assembly installed inside the U-shaped frame, and a clamping plate arranged at the end of the telescopic assembly far away from the U-shaped frame; the two groups of clamping plates move closer to or away from each other under the drive of their respective telescopic assemblies.

[0011] In some possible implementation manners, the telescopic assembly is a scissor jack.

[0012] In some possible implementation manners, the U-shaped frame includes two groups of symmetrically arranged vertical plates, and a horizontal plate located between the two groups of vertical plates and respectively connected to the two groups of vertical plates; the two groups of clamping members are arranged on the side where the two groups of vertical plates are close to each other and are symmetrically arranged.

[0013] In some possible embodiments, arc-shaped grooves are respectively provided on two sets of vertical plates, and there are two sets of limiting rods, and both ends of each limiting rod pass through the two sets of arc-shaped grooves respectively.

[0014] In some possible embodiments, threads are provided at both ends of the limiting rod.

[0015] In some possible embodiments, the center of the arc-shaped groove is arranged on one side close to or far from the cross plate.

[0016] In some possible embodiments, a connecting rod is installed on the cross plate. When the connecting rod is arranged vertically, the axis of the connecting rod, the center of the arc-shaped groove, and the center of the adjusting plate are in the same plane.

[0017] A hanging basket includes the counterweightless hanging basket rear support device as described above, a front support, a cross beam respectively connected to the counterweightless hanging basket rear support device and the front support, an upper support column located on the cross beam, and a hanging basket body.

[0018] In some possible embodiments, the front support includes a support body and a connecting rod installed on the support body and coaxially arranged with the upper support column. One end of the connecting rod far from the support body is connected to the cross beam.

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

[0020] (1) By arranging the U-shaped frame on the roof frame beam, the present utility model effectively solves the problem that the height distance between the roof frame beam and the roof surface at the construction site is too large, far exceeding the installation height of the hanging basket rear support itself.

[0021] (2) By providing the clamping member and the limiting rod, the whole device can firmly adhere to the roof frame beam, effectively preventing the problem that due to the existence of the roof frame beam in some buildings, the length of the hanging basket rear support is too long, resulting in the hanging basket being prone to instability and tipping during operation, and thus causing safety accidents.

[0022] (3) By being fixed on the roof frame beam, the present utility model does not require additional counterweight, and its anti-overturning ability is much stronger than that of the hanging basket rear support with counterweight. Description of the Drawings

[0030] The present utility model will be described in detail below.

[0031] As Figures 1 - 4 shown:

[0032] A counterweightless hanging basket rear support device is sleeved on the outside of the frame beam 100; it includes a U-shaped frame 1 provided with an installation cavity 11, two groups of clamping members 2 installed symmetrically in the U-shaped frame 1, and a limiting rod 3 connected to the U-shaped frame 1 and cooperating with the clamping members 2 and the U-shaped frame 1 to form a clamping cavity; the frame beam 100 is located in the clamping cavity.

[0033] Specifically, the installation cavity 11 is in a U-shaped structure with an opening facing downward;

[0034] During use, first, the frame beam 100 is sleeved in the clamping cavity, and the inner bottom of the U-shaped frame 1 is in contact with the top surface of the frame beam 100. Subsequently, the frame beam 100 is clamped on both sides along its length direction through the clamping assembly. After the clamping is fixed in place, the limiting rod 3 abuts against the bottom of the frame beam 100, thereby fixing the U-shaped frame 1 respectively in the horizontal direction and the vertical direction, making it form an integral body with the frame beam 100. Compared with the prior art, using this structure to cooperate with the frame beam 100 does not require adding counterweights, and the anti-overturning ability is much stronger than that of the counterweighted hanging basket rear support 41, effectively preventing the hanging basket from being prone to instability and tipping during work, and further causing safety accidents.

[0035] In some possible implementation manners, in order to effectively connect and fix the U-shaped frame 1 and the frame beam 100 in the horizontal direction;

[0036] The clamping member 2 includes a telescopic assembly 22 installed in the U-shaped frame 1 and a clamping plate 21 provided at one end of the telescopic assembly 22 away from the U-shaped frame 1. The two groups of clamping plates 21 move closer to or away from each other under the drive of their respective telescopic assemblies 22.

[0037] One end of the telescopic assembly 22 is installed on the U-shaped frame 1 and the other end is connected to the clamping plate 21. The clamping plate 21 is located in the installation cavity 11. The two groups of clamping plates 21 can be made to move closer to or away from each other through the telescoping of the two groups of telescopic assemblies 22, thereby realizing the clamping and fixing of the frame beam 100 with different cross-sectional width dimensions.

[0038] In some possible implementation manners, the telescopic assembly 22 is a scissor jack. The scissor jack in the prior art is used because of its simple structure, light weight, easy to carry, strong load-bearing capacity, good stability, safety and reliability, and high cost performance, and can effectively drive the clamping plate 21 to apply sufficient clamping force to the frame beam 100.

[0039] In some possible implementation manners, in order to effectively sleeve the U-shaped frame 1 outside the frame beam 100;

[0040] The U-shaped frame 1 includes two groups of symmetrically arranged vertical plates 101 and a cross plate 102 located between the two groups of vertical plates 101 and respectively connected to the two groups of vertical plates 101. The two groups of clamping members 2 are arranged symmetrically on the side where the two groups of vertical plates 101 are close to each other.

[0041] The two groups of vertical plates 101 and the cross plate 102 cooperate to form a U-shaped structure with the opening facing downwards. During installation, the bottom of the cross plate 102 will be in contact with the top surface of the frame beam 100. The two groups of clamping members 2 are installed on the two groups of vertical plates 101, and the two groups of clamping plates 21 and the cross plate 102 will form a clamping cavity.

[0042] In some possible embodiments, in order to effectively fix the bottom of the frame beam 100 with different height dimensions through the limiting rod 3; arc-shaped grooves 12 are respectively arranged on two groups of vertical plates 101, the limiting rod 3 is in two groups and both ends respectively pass through the two groups of arc-shaped grooves 12; threads are arranged at both ends of the limiting rod 3, and the arc-shaped groove 12 communicates with the installation cavity 11.

[0043] Preferably, when the U-shaped frame 1 is sleeved outside the frame beam 100 and the top of the frame beam 100 contacts and abuts against the bottom of the cross plate 102, first, the two sides of the frame beam 100 are clamped by two groups of clamping members 2, and then one group of limiting rods 3 is moved along the arc track of the arc-shaped groove 12 so that the limiting rod 3 moves to the bottom of the frame beam 100 and contacts and abuts, and then the limiting rod 3 is fixed by using the cooperation of the nut and the thread; then the other group of limiting rods 3 is fixed;

[0044] The two groups of arc-shaped grooves 12 are symmetrically arranged, and the two groups of limiting rods 3 will prevent the U-shaped frame 1 from moving vertically, and the arrangement of the two groups of clamping members 2 will prevent the U-shaped frame 1 from moving horizontally; thus, the connection between the U-shaped frame 1 and the frame beam 100 is reliable and the position will not change;

[0045] At the same time, since the clamping plates 21 in the two groups of clamping members 2 can approach or move away from each other under the drive of the telescopic assembly 22, and the limiting rod 3 moves along the arc track in the arc-shaped groove 12, it is thus possible to be applicable to cooperate with frame beams 100 with different cross-sectional dimensions.

[0046] In some possible embodiments, the center of the arc-shaped groove is arranged on one side close to or far from the cross plate 102, that is, the opening of the arc-shaped groove is arranged on one side close to or far from the cross plate 102.

[0047] When the center of the arc-shaped groove 12 is arranged on the side close to the cross plate 102, the smaller the distance between the two groups of limiting rods 3, the more the bottom limit of the frame beam 100 with a larger height h dimension of the frame beam 100 is realized, and vice versa, the bottom limit of the frame beam 100 with a smaller height h dimension of the frame beam 100 is realized;

[0048] When the center of the arc-shaped groove 12 is arranged on the side far from the cross plate 102, the smaller the distance between the two groups of limiting rods 3, the more the bottom limit of the frame beam 100 with a larger height h dimension of the frame beam 100 is realized, and vice versa, the bottom limit of the frame beam 100 with a smaller height h dimension is realized.

[0049] In some possible embodiments, to effectively implement the connection between the U-shaped frame 1 and the middle cross beam 30 of the hanging basket; a connecting rod 4 is installed on the transverse plate 102. When the connecting rod 4 is vertically arranged, the axis of the connecting rod 4, the center of the arc-shaped groove 12, and the center of the adjusting plate are in the same plane, and at the same time, the vertical central axis of the U-shaped frame 1 is in this plane.

[0050] Specifically, the connecting rod 4 and the transverse plate 102 are connected in a hinged manner, and a hinge seat 13 is arranged on the transverse plate 102;

[0051] A support 41 with a U-shaped card slot is arranged at one end of the connecting rod 4 far from the transverse plate 102.

[0052] During installation, first connect the connecting rod 4 with the transverse plate 102 of the U-shaped frame 1, then fix and connect the U-shaped card slot to the cross beam 30 through a screw and nut. The open U-shaped frame 1 is sleeved from the top of the frame beam 100, and then by controlling the limit rod joint of the scissors jack and according to the slope of the frame beam 100, adjust the distance between the two clamping plates 21 so that the two clamping plates 21 are pressed against both sides of the frame beam 100 to prevent the hanging basket from shaking. Finally, move the limit rod 3 along the arc track of the arc-shaped groove 12 to press against the bottom of the frame beam 100 and tighten the nuts on both sides of the limit rod 3, so that the entire device is firmly fixed on the frame beam 100 to ensure the stability of the hanging basket during operation.

[0053] A hanging basket includes the non-counterweight hanging basket rear support device as described above, a front support 20, a cross beam 30 respectively connected to the non-counterweight hanging basket rear support device and the front support 20, an upper support column 40 located on the cross beam 30, and a hanging basket body 50.

[0054] In some possible embodiments, the front support 20 includes a support 41 body and a connecting rod installed on the support 41 body and coaxially arranged with the upper support column 40. One end of the connecting rod far from the support 41 body is connected to the cross beam 30.

[0055] Specifically, during installation, the front support 20 will be connected to a group of frame beams 100, and the non-counterweight hanging basket rear support device will be connected to another group of frame beams 100.

[0056] The present utility model is not limited to the foregoing specific embodiments. The present utility model extends to any new feature disclosed in this specification or any new combination, as well as any new method or process step disclosed or any new combination.
