Description

Technical Field

[0001] This utility model relates to the field of engineering construction technology, and specifically to a lifting device. Background Technology

[0002] Lifting devices can be used in various construction projects, especially in the construction of buildings, roof structures, electromechanical equipment, pipelines and decorations of industrial plants, sports venues, exhibition halls and airport terminals, for the transfer, lifting and hoisting of materials, pipelines and equipment.

[0003] Existing lifting devices, such as cranes, have the problem of occupying a large space, while indoor work sites are generally more complex, with various professional operations overlapping and conflicting with horizontal and vertical transportation and operations, which undoubtedly makes them unsuitable for use. Utility Model Content

[0004] The purpose of this utility model is to overcome the defects of the prior art and provide a lifting device that solves the problem that the existing lifting devices occupy a large space and cannot be adapted to complex indoor spaces.

[0005] To achieve the above objectives, this utility model provides a lifting device, which, considering the complex indoor space, is connected to a steel beam for lifting objects. The lifting device includes a hoisting rail, a hinged seat, an inverted clamp, a first upright frame, and a hoisting hoist; wherein,

[0006] The hoisting track is horizontally arranged;

[0007] The hinged seat and the first upright are respectively connected to the upper sides of both ends of the hoisting rail, and each corresponds to any two of the steel beams;

[0008] The inverted clamps are respectively connected to the top of the hinged seat and the first upright, and respectively cooperate with the steel beams at the corresponding positions;

[0009] The hoist is connected to the lower side of the hoisting track and can be adjusted horizontally along the hoisting track.

[0010] By adopting this technical solution, the hoisting track with hoisting hoisting is connected to the steel beam at the corresponding position through the hinged seat and the first upright frame through the inverted clamp, forming a lifting device connected to the steel beam. This can meet the lifting needs of objects through hoisting hoisting, without occupying a large space, and can adapt to various complex indoor space conditions.

[0011] Furthermore, the inverted clamp includes symmetrically arranged jaws and a pin that rotatably connects the two jaws;

[0012] The gripper is V-shaped with one side longer than the other. The openings of the two grippers face each other, and the long side ends are rotatably connected to the pin.

[0013] The pins are respectively connected to the hinge seat and the top of the first upright.

[0014] By adopting this technical solution, the grippers of the inverted clamp are in a movable state relative to the pin. After the pin is subjected to the downward force generated by the hinge seat, the first upright, the lifting rail and the weight of the lifting hoist itself, the two opposing grippers will generate a resultant force to clamp the two sides of the steel beam to complete the connection with the steel beam. Moreover, this resultant force will increase after the lifting hoist is loaded, thereby increasing the stability of the connection between the inverted clamp and the steel beam. Conversely, the two grippers can be separated simply by pushing the lifting rail upward, which has the function of quick assembly and disassembly.

[0015] Furthermore, the first support frame includes an inverted triangular frame whose facade is perpendicular to the length direction of the hoisting track, and a first connecting seat connected to the bottom end of the inverted triangular frame;

[0016] The inverted tripod is connected to the upper end of the hoisting rail via the first connecting seat;

[0017] The inverted clamp is connected to at least two units along the length of the top of the inverted tripod.

[0018] By adopting this technical solution, the inverted tripod is configured such that at least two inverted clamps connected to its top are arranged in a triangle with one inverted clamp connected to the hinged seat, thereby increasing the stability of the lifting device after it is connected to the steel beam.

[0019] Furthermore, the first connecting seat is bolted to the top of the hoisting rail;

[0020] The top of the hoisting track has bolt holes evenly distributed along its length for engaging with bolts.

[0021] By adopting this technical solution, the first erector is detachable on the hoisting track, and its position on the hoisting track can be adjusted according to the actual position of the indoor steel beams.

[0022] Furthermore, it also includes a second support frame;

[0023] The second support frame includes an upright tripod whose facade is vertically aligned with the length of the hoisting track, and a second connecting seat connected to the bottom of the upright tripod;

[0024] The upright tripod is connected to the top of the hoisting rail via the second connecting seat;

[0025] The top of the upright tripod is connected to an inverted clamp, which is then connected to another steel beam.

[0026] By adopting this technical solution, a second upright frame, which is mainly an upright tripod, is added and connected to an inverted clamp and an additional steel beam, further increasing the stability of the overall lifting device and the connection with the steel beam.

[0027] Furthermore, the second connecting seat is fixedly connected to the top of the hoisting rail by bolts through bolt holes opened at the top of the hoisting rail.

[0028] By adopting this technical solution, the second support frame has an adjustable position at the top of the hoisting track, which can adapt to steel beams in different positions for corresponding connections.

[0029] Furthermore, the hoisting track is provided with a groove inside, and an opening at the bottom connects the groove to the outside;

[0030] The top of the hoist extends into the chute through an opening and is slidably connected inside the chute.

[0031] Both ends of the hoisting track are equipped with sealing plates to block the sliding grooves.

[0032] By adopting this technical solution, the design of the chute and opening enables the hoist to move on the hoisting track to accommodate the lifting of objects in different positions. At the same time, the installation of a sealing plate limits the range of motion of the hoist to prevent it from detaching from the hoisting track and causing safety hazards.

[0033] Compared with the prior art, this utility model has the following advantages:

[0034] 1. The hoisting track with hoisting hoist is connected to the steel beam at the corresponding position through the hinge seat and the first upright frame through the inverted clamp, forming a lifting device connected to the steel beam. It can meet the lifting needs of objects through hoisting hoist, and does not occupy a large space. It can adapt to various complex indoor space conditions.

[0035] 2. The hoisting track of the main structure of the lifting device can be equipped with hinged seats, first and second uprights, and inverted clamps to cooperate with indoor steel beams. It can adapt to different steel beam positions and heights through different combinations to ensure the horizontal installation of the hoisting track, which has high flexibility and applicability.

[0042] The present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0043] Example 1:

[0044] This embodiment applies to situations where the indoor steel beam 1 is at different heights. Please refer to the appendix. Figure 1 A lifting device, designed for complex indoor spaces, is connected to a steel beam 1 for lifting objects. The lifting device includes a hoisting rail 2, a hinged seat 3, an inverted clamp 4, a first upright frame 5, and a hoisting hoist 6. The hoisting rail 2 is horizontally positioned. The hinged seat 3 and the first upright frame 5 are connected to the upper sides of both ends of the hoisting rail 2, each corresponding to any two steel beams 1. The inverted clamp 4 is connected to the tops of the hinged seat 3 and the first upright frame 5, respectively, and engages with the corresponding steel beams 1. The hoisting hoist 6 is connected to the lower side of the hoisting rail 2 and can be adjusted horizontally along the hoisting rail 2.

[0045] The hoisting track 2 with hoisting hoist 6 is connected to the steel beam 1 at the corresponding position through the hinge seat 3 and the first upright frame 5 via the inverted clamp 4, forming a lifting device connected to the steel beam 1. This device can meet the lifting needs of objects through hoisting hoist 6 without occupying a large space, and can adapt to various complex indoor space conditions.

[0046] Please see the appendix Figure 2 and 4 The inverted clamp 4 includes symmetrically arranged jaws 41 and a pin 42 rotatably connecting the two jaws 41; the jaws 41 are V-shaped with one side longer than the other side, the openings of the two jaws 41 are facing each other, and the long side ends are rotatably connected to the pin 42 respectively; the pin 42 is respectively connected to the top of the hinge seat 3 and the first upright 5.

[0047] The jaws 41 of the inverted clamp 4 are in an active state relative to the pin 42. After the pin 42 is subjected to the downward force generated by the hinge seat 3, the first upright 5, the lifting rail 2 and the weight of the lifting hoist 6, the two jaws 41 with their openings facing each other will generate a resultant force to clamp the two sides of the steel beam 1 to complete the connection with the steel beam 1. This resultant force will increase after the lifting hoist 6 is loaded, thereby increasing the stability of the connection between the inverted clamp 4 and the steel beam 1. Conversely, the two jaws 41 can be separated by simply pushing the lifting rail 2 upward, which has the function of quick assembly and disassembly.

[0048] Please see the appendix Figure 1-3 The first upright frame 5 includes an inverted tripod with its facade perpendicular to the length direction of the hoisting rail 2 and a first connecting seat 51 connected to the bottom end of the inverted tripod; the inverted tripod is connected to the upper side of the end of the hoisting rail 2 through the first connecting seat 51; at least two inverted clamps 4 are connected along the length direction of the top of the inverted tripod.

[0049] The inverted tripod is designed so that at least two inverted clamps 4 connected to its top can be triangularly distributed with one inverted clamp 4 connected to the hinge seat 3, thereby increasing the stability of the lifting device after it is connected to the steel beam 1.

[0050] Furthermore, the first connecting seat 51 is bolted to the top of the hoisting rail 2; the top of the hoisting rail 2 is evenly provided with bolt holes that mate with the bolts along its length; this makes the first upright 5 detachable on the hoisting rail 2, and the position of the first upright 5 on the hoisting rail 2 can be adjusted according to the actual position of the indoor steel beam 1.

[0051] Furthermore, it also includes a second upright frame 7; the second upright frame 7 includes an upright tripod whose facade is vertically aligned with the length of the hoisting rail 2 and a second connecting seat 71 connected to the bottom of the upright tripod. The second connecting seat 71 is fixedly connected to the top of the hoisting rail 2 by bolts through bolt holes opened at the top of the hoisting rail 2; the upright tripod is connected to the top of the hoisting rail 2 through the second connecting seat 71; the top of the upright tripod is connected to an inverted clamp 4, and is connected to another steel beam 1 through the inverted clamp 4; the addition of a second upright frame 7 with an upright tripod as its main body and the inverted clamp 4 to connect with an additional steel beam 1 further increases the stability of the connection between the hoisting device and the steel beam 1.

[0052] The hoisting rail 2 has a groove inside, and an opening at the bottom connecting the groove to the outside. The top of the hoisting hoist 6 extends into the groove through the opening and is slidably connected inside the groove. Both ends of the hoisting rail 2 are equipped with sealing plates to block the groove. The groove and the opening enable the hoisting hoist 6 to move on the hoisting rail 2 to accommodate the lifting of objects in different positions. At the same time, the sealing plates limit the range of motion of the hoisting hoist 6 to prevent the hoisting hoist 6 from detaching from the hoisting rail 2 and causing safety hazards.

[0053] Furthermore, to facilitate the maintenance and replacement of the hoist 6, the sealing plate connected to the end of the hoisting rail 2 can be made detachable.

[0054] It should be noted that, in order to ensure the stability of the lifting device connection, the steel beam 1 should have a section with a relatively thin longitudinal thickness to cooperate with the inverted clamp 4, with I-beams being the best connection method. The above embodiment is an installation method adapted to different heights of the indoor steel beam 1, and is not the only installation method. For example, only the hinge seat 3 and the first upright 5 are installed on the hoisting rail 2 and are respectively connected to the steel beam 1 with the inverted clamp 4; only the hinge seat 3 and the second upright 7 are installed on the hoisting rail 2 and are respectively connected to the steel beam 1 with the inverted clamp 4; and only the first upright 5 and the second upright 7 are installed on the hoisting rail 3 and are respectively connected to the steel beam 1 with the inverted clamp 4.

[0055] Example 2:

[0056] This embodiment is applicable to situations where indoor steel beams 1 are at the same height. Based on the specific connection methods and structures of the relevant components in Embodiment 1, it includes three implementation methods: 1. Only hinged seats 3 are installed on the hoisting rail 2, and the steel beam 1 is connected by at least two hinged seats 3 in conjunction with the inverted clamp 4; 2. Only the first upright 5 is installed on the hoisting rail 2, and the steel beam 1 is connected by at least two first upright 5 in conjunction with the inverted clamp 4; 3. Only the second upright 7 is installed on the hoisting rail 2, and the steel beam 1 is connected by at least two second upright 7 in conjunction with the inverted clamp 4.

[0057] Example 3:

[0058] This embodiment is based on Embodiment 1 and adapts to the installation of the lifting device on U-shaped beams 8 at different heights. The inverted clamp 4 is adjusted to a structure in which a single clamp 41 connects to the pin 42. That is, the structure below the pin 42 is exactly the same as the structure below the pin 42 in Embodiment 1. The pin 42 and the U-shaped beam 8 are connected by a single clamp 41. In order to ensure the stability of the lifting device after using a single clamp 41 to connect with the U-shaped beam 8, at least one of the three clamps 41 on the hinge seat 3, the first upright 5 and the second upright 7 is set in the opposite direction to the other two clamps 41. That is, the three corresponding U-shaped beams 8 are either facing each other or facing away from each other.

[0059] Example 4:

[0060] This embodiment is applicable to situations where indoor U-shaped beams 8 are at the same height. Based on the specific connection methods and structures of the relevant components in Embodiment 3, it includes three implementation methods: 1. Only hinged seats 3 are installed on the hoisting rail 2, and the steel beam 1 is connected by at least two hinged seats 3 in conjunction with the inverted clamp 4 of a single gripper 41; 2. Only first uprights 5 are installed on the hoisting rail 2, and the steel beam 1 is connected by at least two first uprights 5 in conjunction with the inverted clamp 4 of a single gripper 41; 3. Only second uprights 7 are installed on the hoisting rail 2, and the steel beam 1 is connected by at least two second uprights 7 in conjunction with the inverted clamp 4 of a single gripper 41.

[0061] In the above three embodiments, at least two hinged seats 3, at least two first uprights 5 and at least two second uprights 7 are connected to at least two single grippers 41 with inverted clamps 4, where any two grippers 41 face each other or back to back, in order to ensure the stability of the connection between the lifting device and the U-shaped beam 8.

[0062] The present invention has been described in detail above with reference to the accompanying drawings and embodiments. Those skilled in the art can make various modifications to the present invention based on the above description. Therefore, certain details in the embodiments should not be construed as limiting the present invention, and the scope of protection of the present invention shall be defined by the appended claims.
