Description

TECHNICAL FIELD

[0001] The utility model belongs to the technical field of building auxiliary facilities, and particularly relates to a hoisting connecting piece. BACKGROUND

[0002] The finished product support is a support assembly produced by a factory, which is directly produced into a shaped channel steel and various connecting pieces, and then is assembled on site by construction personnel. The support assembly can be used for supporting various pipelines and pipe lines, and has important significance in indoor installation of buildings.

[0003] However, in actual application, after the assembly of the support assembly is completed, it needs to be hoisted to the top of the room. At this time, since the pipelines on each support assembly need to be connected with each other, the height and position accuracy of hoisting are required to be high. The traditional hoisting method is to use a hoisting machine to hoist the support assembly to a specified position, and then manually adjust it and fix the support assembly to the wall. This method has many problems: on the one hand, the operation process is complicated, and multiple people are required to cooperate, which is low in construction efficiency; on the other hand, the hoisting machine needs to work continuously to keep the support assembly in the position, which not only increases the energy consumption and wear of the equipment, but also puts forward higher requirements for the working performance of the hoisting machine, and also has certain safety hazards.

[0004] In addition, when the traditional hoisting method is used for high-altitude operation, due to the limited accuracy of manual adjustment, it is difficult to ensure the position and height accuracy of the support assembly during hoisting, which is easy to cause misalignment or stress concentration at the pipeline connection, and thus affects the stability and service life of the entire pipeline system. Therefore, developing a hoisting device capable of improving the hoisting efficiency, reducing manual intervention, and ensuring the hoisting accuracy of the support assembly has important practical significance in the field of indoor pipeline installation of buildings. UTILITY MODEL CONTENTS

[0005] The utility model aims at providing a hoisting connecting piece to improve the stability and convenience of installation of the support assembly.

[0006] In order to solve the above-mentioned technical problems, the utility model specifically adopts the following technical solutions:

[0007] A hoisting connecting piece, comprising a baffle and a main body in the shape of a "door", a first installation area and a second installation area are arranged at a first end and a second end of the main body respectively, the second installation area is inclined to form an inclined structure away from the center line of the main body, so that the spacing between the first installation area and the second installation area gradually increases from top to bottom; the second end of the baffle is rotationally arranged at the second end of the second installation area, and the first installation area is provided with a limiting hole;

[0008] One part of the baffle is located in the limiting hole under no external force, and the baffle and the main body enclose an installation space for accommodating the support assembly;

[0009] When the support assembly is loaded into the installation space from bottom to top, the baffle rotates in a first direction under the action of the support assembly to form an opening at the bottom of the installation space, and when the support assembly completely enters the installation space and is located above the baffle, the baffle rotates in a second direction under the action of its own gravity to reset and restrict the support assembly in the installation space.

[0010] As an improvement, the limiting hole comprises a limiting part and a movable part arranged in sequence from top to bottom, the width of the limiting part is smaller than the width of the movable part, the first end of the baffle extends outward of the installation space to form a limiting block, and the width of the limiting block is greater than the width of the limiting part and smaller than the width of the movable part.

[0011] As an improvement, an arc-shaped transition structure is arranged between the limiting part and the movable part.

[0012] As an improvement, the second end of the second installation area is provided with a rotating groove, and the second end of the baffle is arranged in the rotating groove through a rotating shaft.

[0013] As an improvement, at least one side of the main body is provided with a fixing hole, when the first end of a fixing member is inserted into the fixing hole, the first end of the fixing member abuts against the support assembly, and the second end of the fixing member is located outside the installation space.

[0014] As an improvement, two fixing holes are arranged on both sides of the main body.

[0015] As an improvement, the two fixing holes are symmetric about the central axis of the main body.

[0016] As an improvement, the two sides of the rotating groove are respectively provided with a first installation hole, and the first end of the baffle is provided with a second installation hole corresponding to the first installation hole.

[0017] When the rotating shaft passes through the second installation hole and the two first installation holes at the same time, the rotating shaft connects the main body and the baffle, and the baffle can rotate around the rotating shaft.

[0018] As an improvement, the acute angle between the extension line of the inclined structure and the extension line of the height direction of the main body ranges from 10° to 30°.

[0019] As an improvement, the top of the main body is provided with a through hole.

[0020] The principle and beneficial technical effects of the utility model lie in that:

[0021] When installing the support assembly (and the pipeline fixed on the support assembly) in the room, due to the narrow indoor space, large hoisting equipment with high stability cannot be used, and the stability of small hoisting equipment is also insufficient, so the installation relies heavily on manual work, and the stability and safety during installation cannot be guaranteed.

[0022] Therefore, for the case of installing the connecting assembly in the room, the application comprehensively provides a pre-fixed connecting piece capable of automatic opening and closing, which can effectively improve the stability and convenience of component installation.

[0023] Firstly, when installing the support assembly, the baffle is automatically opened to expose the opening in the lifting process of the support assembly, and after the support assembly completely enters the installation space, the baffle automatically falls back to form a semi-closed installation space with both ends open and the periphery closed, so as to limit the support assembly in the installation space; on the one hand, this process does not require manual intervention and is convenient and fast to use; on the other hand, after the support assembly enters the installation space, the hoisting connecting piece in the application can effectively support the support assembly, without the need for the hoisting equipment to continuously exert force on it.

[0024] Further, a plurality of hoisting connecting pieces can be installed to a specified height in advance, so that after the support assembly is installed into the installation space, the support assembly can be automatically aligned, without the need to adjust the heavy support assembly, further improving the convenience of use; in addition, after the support assembly is fixed on the wall, the hoisting connecting piece can continuously support the support assembly to reduce the connection pressure between the support assembly and the wall, thereby improving the installation stability of the support assembly.

[0039] Embodiment one

[0040] The present embodiment is basically as shown in Figures 1-9

[0041] Referring to Figure 1 , the present application provides a hoisting connecting piece, comprising a baffle and a main body 1 in the shape of "door", the first end and the second end of the main body 1 are respectively provided with a first mounting area 3 and a second mounting area 4, the first mounting area 3 and the second mounting area 4 are oppositely arranged, the second mounting area 4 is inclined to the direction away from the center line of the main body to form an inclined structure, so that the distance between the first mounting area 3 and the second mounting area 4 gradually increases from top to bottom; the second end of the baffle 2 is rotatably arranged at the second end of the second mounting area 4, and the first mounting area 3 is provided with a limiting hole.

[0042] Under the action of no external force, one part of the baffle 2 is located in the limiting hole 5, and the baffle 2 and the main body 1 enclose to form a mounting space for accommodating a support assembly.

[0043] ​Specifically, the main body comprises a first portion, a second portion and a third portion connected in sequence, the first portion is parallel to the third portion, the second portion is perpendicular to the second portion, the first mounting area and the second mounting area are located on the first portion and the third portion respectively, wherein the length of the first portion is slightly greater than the length of the third portion, so that when the baffle is in the open state, the main body is in a frame structure similar to a "door" character with one end slightly longer and the other end opening outward, and when the baffle is in the initial state, the baffle is parallel to the second portion, and the baffle and the main body form an installation space similar to a rectangle.

[0044] Referring to Figures 6-8 When the support assembly 6 is loaded into the installation space from bottom to top, the baffle rotates in the first direction under the action of the support assembly 6 to form an opening at the bottom of the installation space, when the support assembly completely enters the installation space and is located above the baffle, the baffle rotates in the second direction under the action of its own gravity to reset, and the support assembly 6 is placed on the baffle, and the support assembly 6 is limited in the installation space; wherein the first direction is opposite to the second direction.

[0045] In some embodiments, referring to Figure 3 , the limiting hole comprises a limiting portion 501 and a movable portion 502 arranged in sequence from top to bottom, the width of the limiting portion 501 is less than the width of the movable portion 502, the limiting portion 501 and the movable portion 502 are communicated, the first end of the baffle extends outward to form a limiting block outside the installation space, the width of the limiting block is greater than the width of the limiting portion 501 and less than the width of the movable portion 502.

[0046] In some embodiments, the width of the part of the baffle between the first mounting area and the second mounting area is greater than the part of the baffle located in the limiting hole, that is, the baffle on both sides of the part corresponding to the limiting hole forms a clamping groove 202; that is, under the action of no external force, a part of the baffle is located in the limiting portion 501, and both ends extend to both sides and increase in width, wherein the limiting block can limit the position of the baffle and the first mounting area, prevent the baffle from deforming under the action of the gravity of the support assembly, or the first mounting area deforms outward along the width direction of the main body, so that the baffle is separated from the limiting portion 501 and exposed. When the baffle is lifted away from the limiting portion 501, the limiting block can enter the inside of the installation space through the movable portion 502, so that the opening is exposed.

[0047] In some embodiments, an arc-shaped transition structure 503 is arranged between the limiting portion 501 and the movable portion 502. Specifically, the arc surface (the outer surface of the circular arc) of the arc-shaped structure faces the inside of the limiting hole. The transition structure 503 is arranged to smoothly transition the limiting portion 501 and the movable portion 502. When the baffle plate falls back to the limiting portion 501 along the second direction, the baffle plate can fall along the transition structure 503 to avoid the situation that the baffle plate deviates slightly and cannot fall into the limiting portion.

[0048] In some embodiments, the second end of the second mounting area is provided with a rotating groove 401, and the second end of the baffle plate is rotatably arranged in the rotating groove 401 through a rotating shaft 402. The two side walls of the rotating groove 401 can limit the baffle plate in the axial direction of the rotating groove 401.

[0049] In some specific embodiments, the two sides of the rotating groove 401 are respectively provided with a first mounting hole 403, and the first end of the baffle plate is provided with a second mounting hole 404 corresponding to the first mounting hole 403. When the rotating shaft 402 passes through the second mounting hole 404 and the two first mounting holes 403 at the same time, the rotating shaft 402 connects the main body and the baffle plate, and the baffle plate can rotate around the rotating shaft.

[0050] Of course, in other embodiments, the baffle plate can also be rotatably connected with the second mounting area through a hinge seat, or connected in other rotating manners. That is, the above-mentioned solutions cannot limit the connection manner of the baffle plate and the second mounting area.

[0051] In some embodiments, referring to Figure 4 , the acute angle between the extension line of the inclined structure 9 and the extension line of the height direction of the main body 1 is an angle α of 10°-30° (preferably 30°). On the one hand, by arranging the inclined structure 9, the opening of the bracket assembly becomes smaller during entering the installation space, which facilitates the bracket assembly to enter from the opening with a larger width. After entering, the end with a smaller width can limit the bracket assembly to prevent the bracket assembly from swinging greatly in the installation space. On the other hand, the design of the inclined structure enables the baffle plate to rotate around the rotating shaft at the end of the inclined structure to a large enough angle, for example, 90°, so that the plane of the baffle plate is parallel to the height direction of the main body in the fully open state, thereby saving the internal space.

[0052] In some embodiments, referring to Figure 2The body 1 is provided with a fixing hole 7 on at least one side thereof; when the first end of a fixing member (e.g. a bolt) is inserted into the fixing hole 7, the first end of the fixing member abuts against the bracket assembly, and the second end of the fixing member is located outside the mounting space (not shown in the figure); the fixing member and the side wall of the body 1 on the opposite side of the fixing hole 7 jointly clamp the bracket assembly to prevent the bracket assembly from shaking in the mounting space.

[0053] In some embodiments, two fixing holes are provided, and the two fixing holes are respectively provided on the two sides of the body. Preferably, the two fixing holes are symmetric about the central axis of the body; at this time, the two oppositely arranged fixing members clamp the bracket assembly to prevent the bracket assembly from shaking in the mounting space.

[0054] In some embodiments, referring to Figure 2 and Figure 6 , the top of the body is provided with a through hole 8; in use, one end of a lead screw 10 is pre-embedded in the wall of the roof, and the other end of the lead screw 10 is connected and fixed to the hoisting connecting member 11 through the through hole 8; by rotating the lead screw 10, the position of the hoisting connecting member 11 relative to the lead screw 10 can be adjusted, i.e. the height of the hoisting connecting member 11 can be adjusted.

[0055] In specific use, referring to Figures 6-9 , the hoisting connecting member 11 is pre-installed on the lead screw 10, and the hoisting connecting member 11 is adjusted to a specified angle by the lead screw 10; then the bracket assembly is lifted by a hoisting device, and the bracket on the top of the bracket assembly enters the mounting space; at this time, the baffle is pushed open by the force of the bracket assembly, and rotates in the first direction about the rotating shaft; as the bracket continues to rise, the bracket completely enters the inside of the mounting space and is higher than the height of the baffle, the bracket no longer contacts the baffle, the force on the baffle disappears, the baffle falls in the second direction under the action of its own gravity, and the baffle and the body are re-enclosed to form a four-side closed mounting space, thereby supporting the bracket; then, the bracket is fixed to the wall 12 by manual operation, and after a plurality of bracket assemblies (and pipes 13 installed on the bracket assemblies) are installed on a plurality of hoisting connecting members 11 by the above method, the plurality of bracket assemblies are conveniently connected.

[0056] In the above process, first, when installing the support assembly, the support assembly automatically pries open the baffle to expose the opening during lifting, and when the support assembly is completely in the installation space, the baffle automatically falls back to form a semi-closed installation space with both ends open and the periphery closed, so as to limit the support assembly in the installation space; on the one hand, this process does not require manual intervention and is convenient and fast; on the other hand, after the support assembly enters the installation space, the hoisting connecting piece in the application can effectively support the support assembly, without the need for the hoisting device to continuously exert force on it.

[0057] Further, by pre-installing a plurality of hoisting connecting pieces to a specified height, the support assembly can be automatically aligned after being installed into the installation space, without the need to adjust the heavy support assembly again, further improving the convenience of use; in addition, after the support assembly is fixed on the wall, the hoisting connecting piece can continuously support the support assembly to reduce the connection pressure between the support assembly and the wall, thereby improving the installation stability of the support assembly.

[0058] In summary, for the case of indoor installation connection assembly, the application comprehensively provides a pre-fixed connecting piece that can automatically open and close, which can effectively improve the stability and convenience of component installation.

[0059] It should be noted that in this document, the terms "comprise", "contain" or any other variant thereof are intended to cover non-exclusive inclusion, so that the process, method, article or device including a series of elements not only includes those elements, but also includes other elements not explicitly listed or inherent to such process, method, article or device. Without more limitations, the element defined by the statement "comprises a" does not exclude the presence of another identical element in the process, method, article or device including the element.

[0060] The embodiments of the application are described above in combination with the drawings, but the application is not limited to the above specific embodiments, and the above specific embodiments are only illustrative and not restrictive, and those skilled in the art can make many forms under the inspiration of the application without departing from the purpose of the application and the scope protected by the claims, which are all within the protection of the application.
