Description

Technical Field

[0001] This invention relates to a socket-type disc-lock steel pipe support frame double-channel steel beam system, belonging to the field of building structure technology. Background Technology

[0002] The double-channel steel support beam is a crucial component of the support frame. As a support element, it plays a vital role in reducing material usage and ensuring the safety and stability of the support frame. Simultaneously, it bears and transmits vertical loads through the upright discs. Its performance directly impacts the probability of safety accidents occurring within the support frame.

[0003] For example, CN217106133U describes a socket-type disc-lock steel pipe support frame with a double-channel steel beam system. This system can be quickly installed using the beam, the first upright and the first adjustable bracket, the second adjustable bracket and the second upright. Furthermore, the height of the main keel can be adjusted by adjusting the first upright and the first adjustable bracket, thus achieving effective support for the support system.

[0004] However, in some situations, the accumulation of debris, the suspension of work, or construction work on the ground make it inconvenient for workers / materials to be transported or transferred between the two ends of the double channel steel; or an electrically driven transport structure is installed on the double channel steel, requiring a structure that can transport and transfer between the two ends of the double channel steel without the use of electricity. Summary of the Invention

[0005] The purpose of this invention is to provide a socket-type disc-lock steel pipe support frame double-channel steel beam system to solve the problems mentioned in the background art.

[0006] The technical solution of the present invention is as follows:

[0007] A socket-type disc-lock steel pipe support frame double-channel steel beam system includes an upright, a double-channel steel beam horizontally installed on the upper end of the upright, an adjustable support at the top of the double-channel steel beam, and further includes:

[0008] The guide rail is rotatably mounted on a double-channel steel support beam via a pivot in the middle.

[0009] A movable seat, on which a guide wheel is movably mounted, the guide wheel rollingly engaging with the upper surface of a guide rail;

[0010] The inclined top seat is provided at both ends of the double channel steel support beam, and the two ends of the guide rail respectively abut against the inclined top surfaces of the two sets of inclined top seats;

[0011] An adjustment assembly is installed on a double-channel steel support beam and is used to adjust the installation position of the two sets of inclined top seats on the double-channel steel support beam.

[0012] Preferably, the guide rail has top blocks at both ends with the bottom facing downwards, and the top blocks are used to abut against the inclined top surface of the inclined top seat.

[0013] Preferably, the guide rail is a rack structure, and the guide wheel is a gear structure that meshes with the rack structure.

[0014] Preferably, a groove extending radially is provided on one side of the guide wheel, a slider is slidably connected in the groove, a heat-conducting braking component is installed on the slider, and the slider is driven to approach the axis of the guide wheel by the elastic force of the first elastic component;

[0015] The movable seat is equipped with brake pads. The rotation of the guide wheel, under its centrifugal force, throws the heat-conducting brake component outward to abut and rub against the brake pads.

[0016] Preferably, the brake pad has a relief groove in the middle and a notch extending from the outer edge of the relief groove to the outer edge of the brake pad.

[0017] Preferably, a limiting groove is formed on the side wall of the slide away from the guide wheel, and a limiting rod is slidably connected inside the slider by a second elastic element. The elastic force of the second elastic element pushes one end of the limiting rod to extend out of the slider.

[0018] The slider is also equipped with a telescopic rod, which contains a thermal expansion and contraction fluid. The thermal expansion and contraction fluid is connected to a heat-conducting braking component through a conduit. When the thermal expansion and contraction fluid is heated, it expands and pushes the telescopic rod to extend. The extension of the telescopic rod pushes the limiting rod to retract into the slider.

[0019] Preferably, a suspended basket is attached to the movable seat.

[0020] Preferably, the inclined top seat is slidably connected to the double-channel steel support beam along the length direction of the double-channel steel support beam.

[0021] Preferably, the adjustment assembly includes a steering rod and steering wheels fixed at both ends of the steering rod. The steering rod is provided with a worm gear portion, and a rack portion that meshes with the corresponding worm gear portion is provided on one side of the inclined top seat.

[0022] Preferably, a pull rope is attached to the outer wall of the steering wheel.

[0023] The present invention has the following beneficial effects:

[0024] No additional power supply is required. The movable seat rolls on the surface of the guide rail via guide wheels and uses gravity to move between the two ends of the double channel steel support beam. Materials can be placed in the basket and passed through and transferred over piles of debris on the ground and in suspended places.

[0025] To avoid impact on the basket caused by excessive speed, centrifugal force is used to create friction between the brake pads and the heat-conducting braking components when the speed reaches a critical value, thereby reducing the moving speed of the movable seat. Attached Figure Description

[0036] The present invention will now be described in detail with reference to the accompanying drawings and specific embodiments.

[0037] Example 1: As Figure 1 As shown:

[0038] The double-channel steel support beam 1 is horizontally installed, with both ends suspended and fixed above the ground by uprights 2. An adjustable support 3 is installed at any point on the double-channel steel support beam 1 to support the building above. This is existing technology and will not be described in detail.

[0039] like Figure 2 As shown, a rotating shaft 71 is provided in the middle of the guide rail 7. The rotating shaft 71 is rotatably connected to the middle of the double channel steel support beam 1. Both ends of the double channel steel support beam 1 are provided with top blocks 72 facing downwards. Both ends of the double channel steel support beam 1 are provided with inclined top seats 8 (symmetrically arranged). The upper surface of the inclined top seats 8 is inclined. The inclined top seats 8 slide linearly along the length of the double channel steel support beam 1. The two sets of top blocks 72 respectively abut against the inclined upper surface of the corresponding inclined top seats 8.

[0040] like Figure 3 As shown, the adjustment assembly 5 includes a steering rod 52 and steering wheels 51 fixedly installed at both ends of the steering rod 52. The axis of the steering rod 52 is parallel to the moving direction of the inclined support seat 8. The steering rod 52 is rotatably connected to the side wall of the double channel steel support beam 1. Both the left and right sides of the steering rod 52 are provided with worm gears, and both sides of the two sets of inclined support seats 8 are provided with racks. The worm gears of the steering rod 52 mesh with the racks of the side walls of the inclined support seats 8, so that the rotation of the steering rod 52 drives the two sets of inclined support seats 8 to move linearly, and the distance between the two sets of inclined support seats 8 remains unchanged.

[0041] like Figure 4 As shown, a pull rope 53 is sleeved on the outer wall of the steering wheel 51. The user can drive the steering wheel 51 at a higher position to rotate by pulling the rope 53 from a lower position. This structure is already widely used in sliding windows in daily life.

[0042] Working principle:

[0043] The rotation of the steering rod 52 drives the two sets of inclined top seats 8 to move linearly on the double channel steel support beam 1, so that the top block 72 of the guide rail 7 abuts against the upper surface of the inclined top seat 8 at different positions, thereby adjusting the tilt state of the guide rail 7, which can be adjusted to left high and right low or right high and left low.

[0044] like Figure 5 As shown, a guide wheel 41 is rotatably connected to the movable seat 4. The guide wheel 41 presses against the upper surface of the corresponding guide rail 7. Due to the structural limitations of the movable seat 4 and the double channel steel support beam 1, the movable seat 4 can move vertically up and down and forward and backward relative to the double channel steel support beam 1, but it cannot move left and right.

[0045] The suspended basket 6 is freely suspended at the bottom of the movable seat 4. The materials are placed inside the suspended basket 6. The weight of the suspended basket 6 and its internal components causes the guide wheel 41 to press against the guide rail 7. Due to the inclined setting of the guide rail 7, the guide wheel 41, which rolls freely on the guide rail 7, rolls downwards under the action of gravity, thereby realizing the transportation of materials between the two ends of the double channel steel support beam 1 without the need for electricity.

[0046] Example 2: Includes all the content of Example 1:

[0047] Since the suspended basket 6 is freely suspended at the bottom of the movable seat 4, if the movable seat 4 moves too fast, the impact force will be large when it reaches the lower limit, which can easily cause damage. The materials inside the suspended basket 6 are also prone to collision damage due to sudden stops.

[0048] like Figure 5-7 As shown, the guide rail 7 is configured as a rack and pinion structure, and the guide wheel 41 is configured as a gear structure. The rack and pinion guide rail 7 meshes with the gear guide wheel 41. A groove 411 is provided on the side wall of the guide wheel 41, extending radially along the guide wheel 41. The slider 42 slides linearly within the groove 411. A heat-conducting braking component 44 is fixedly mounted on the slider 42. A first elastic component 43 (tension spring) connects the slider 42 and the groove 411. A brake pad 9 is detachably mounted on the movable seat 4 via a bolt assembly, facilitating the replacement of the brake pad 9. Figure 7 As shown, a clearance groove 91 is provided on the side of the brake pad 9 near the guide wheel 41;

[0049] When the guide wheel 41 rotates too fast, the centrifugal force causes the slider 42 to be thrown outward, causing the thermally conductive braking component 44 on the slider 42 to follow and come into contact with the brake pad 9. At the same time, the first elastic component 43 is stretched to generate a reverse elastic force. The friction generated by the thermally conductive braking component 44 coming into contact with the brake pad 9 reduces the speed of the movable seat 4, but it can still move forward slowly.

[0050] When the speed of the guide wheel 41 has not reached the maximum set value, the slider 42 is positioned relative to the clearance groove 91.

[0051] Example 3: Includes all the contents of Example 2;

[0052] In Embodiment 2, although the speed of the guide wheel 41 can be prevented from exceeding the set value, the speed of the guide wheel 41 always hovers near the maximum set value, maintaining a relatively high speed.

[0053] like Figure 5-8 As shown, a limiting groove 412 is formed on the side of the slide groove 411 away from the axis of the guide wheel 41, such as... Figure 8 As shown, a horizontal plate 47 is linearly slidably connected to the inner cavity of the slider 42. A second elastic element 48 is connected between the horizontal plate 47 and the inner cavity of the slider 42. A limit rod 45 is fixedly installed on the horizontal plate 47 and passes through the slider 42 along its length direction. Thus, under normal conditions, one end of the limit rod 45 moves to the outside of the slider 42 under the action of the elastic force of the second elastic element 48.

[0054] When the guide wheel 41 rotates too fast and reaches the set value, the slider 42 is thrown outward. Under the elastic force of the second elastic element 48, one end of the limiting rod 45 is inserted into the limiting groove 412. After that, even if the rotation speed of the guide wheel 41 decreases, the first elastic element 43 cannot drive the slider 42 to reverse and reset. Figure 8As shown, a telescopic rod 46 is installed inside the slider 42. The inner cavity of the telescopic rod 46 is filled with a thermal expansion and contraction fluid, and the thermal expansion and contraction fluid is connected to one side of the thermally conductive braking component 44 through a conduit.

[0055] Working principle: The thermally conductive braking component 44 rotates relative to the brake pad 9. The friction between them causes the thermally conductive braking component 44 to heat up. The heat generated by the thermally conductive braking component 44 is transferred to the thermal expansion and contraction fluid. The thermal expansion and contraction fluid expands due to heat, pushing the telescopic rod 46 to extend. The extension of the telescopic rod 46 passes through the horizontal plate 47 and drives the free end of the limiting rod 45 to retract into the slider 42, thereby realizing that the free end of the limiting rod 45 is pulled out from the limiting groove 412. Then, under the action of the elastic force of the first elastic component 43, the slider 42 is driven to reverse and reset.

[0056] The above settings allow the heat-conducting braking component 44 to rotate relative to the brake pad 9 for a period of time, reducing the speed of the guide wheel 41 from high to low, far below the maximum setting value, which is beneficial to safety.

[0057] Multiple heat dissipation holes are provided on the slider 42. Then, the heat-conducting brake 44 is separated from the brake pad 9. The heat-conducting brake 44 is cooled by natural air. The thermal expansion and contraction fluid is shortened by cooling. Under the push of the elastic force of the second elastic member 48, the free end of the limit rod 45 tends to extend to the outside of the slider 42.

[0058] Example 4 includes all the contents of Example 3:

[0059] Because there is friction between the brake pad 9 and the heat-conducting braking component 44, the centrifugal force required to push the heat-conducting braking component 44 outward to contact the brake pad 9 is relatively large. Figure 7 As shown, a notch 92 is provided from the outer edge of the clearance groove 91 to the outer edge of the brake pad 9. Chamfers are provided on both sides of the notch 92. This notch 92 is slightly larger than the width of the heat-conducting brake component 44. Thus, when the guide wheel 41 is moving too fast and throws the slider 42 and the heat-conducting brake component 44 outward, the heat-conducting brake component 44 can first enter the notch 92, and then normally abut against the brake pad 9 from the chamfer to generate friction.

[0060] like Figure 6-7 As shown, several sliders 42 / thermal brake elements 44 are arranged in a ring around the axis of the guide wheel 41, and several notches 92 are arranged in a ring around the axis of the brake pads 9. The brake pads 9 are aligned with the axis of the guide wheel 41, and the number of brake pads 9 is different from the number of thermal brake elements 44. For example, there are three sets of thermal brake elements 44 and four sets of brake pads 9. Thus, only one thermal brake element 44 can smoothly enter the notch 92 at the same time. This thermal brake element 44 makes contact friction with the brake pads 9, so that the centrifugal force of other subsequent thermal brake elements 44 is insufficient to enter the notch 92. This is beneficial because only one set of thermal brake elements 44 is in use, which is beneficial for the other sets of thermal brake elements 44 to dissipate heat and cool down.

[0061] The above description is merely an embodiment of the present invention and does not limit the patent scope of the present invention. Any equivalent structural or procedural transformations made based on the content of the present invention's specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of the present invention.
