Description

Technical Field

[0001] This invention relates to the field of fixed building equipment technology, specifically to an auxiliary fixing device and fixing method for the installation of energy-saving door and window frames. Background Technology

[0002] In the field of building door and window installation, traditional window frame installation relies heavily on manual handling, lifting, and alignment, which is inefficient and poses safety hazards. Especially in high-rise buildings or batch installations, workers need to lift heavy door and window frames for extended periods of time for positioning, resulting in high labor intensity and difficulty in ensuring installation accuracy.

[0003] Patent application CN202211511682.3 discloses a window frame installation device, including two mounting plates. Each mounting plate has an adsorption mounting positioning component for attaching and fixing to the walls on both sides of a window. The adsorption mounting positioning component has a lifting mounting mechanism for fixing the window frame and raising it for precise installation. This window frame installation device, through its adsorption mounting positioning components, facilitates the symmetrical positioning of the mounting plates on both sides of the window, simultaneously positioning the frame left and right and top, ensuring installation accuracy.

[0004] Currently, some installation aids exist, such as the window frame installation device disclosed in Chinese patent application CN202211511682.3, which uses adsorption installation positioning components to fix the device to both sides of the window on the wall for positioning and installation. However, in actual use, this type of adsorption device is greatly affected by the condition of the wall surface: if the wall surface has dust, unevenness, or peeling coating, the adsorption force will decrease significantly, resulting in unstable positioning, affecting installation accuracy, and even posing a risk of falling off.

[0005] Furthermore, such devices primarily focus on the final positioning stage and do not effectively address the labor-saving issues during the handling, transfer, and initial alignment of door and window frames, resulting in a still relatively cumbersome overall installation process. Therefore, there is an urgent need for an energy-efficient door and window frame installation and fixing device that can adapt to different wall conditions, provide full assistance from handling to positioning, and offer stable and reliable operation. Summary of the Invention

[0006] In order to overcome the defects in the prior art, the present invention aims to provide an auxiliary fixing device and fixing method for the installation of energy-saving door and window frames. The overall structure adopts mechanical fixing and adjustment, avoiding reliance on wall adsorption, overcoming the problem of unstable adsorption caused by dust or unevenness of the wall surface in the prior art, and ensuring reliable operation under various wall conditions, so as to solve the problems mentioned in the background art.

[0007] To achieve the above objectives, the present invention provides an auxiliary fixing device for the installation of energy-saving door and window frames, including a loading vehicle for placing the door and window frames and clamping parts symmetrically arranged above the loading vehicle for clamping door and window frames of different widths and moving them to the installation area.

[0008] The loading vehicle is symmetrically and fixedly equipped with square frame-shaped handrails on its left and right sides. The loading vehicle is fixedly equipped with a backrest in a backward-leaning position at its rear. When a pallet rack is placed on the top surface of the loading vehicle, it is used to support the door frame. When a pallet rack is placed in the middle area of ​​the front side of the backrest, it is used to support the window frame.

[0009] The clamping part slides back and forth along the top rod of the support frame to transfer the door and window frame inside the loading vehicle; the clamping part includes a longitudinal support rod that slides on the top rod of the support frame and is positioned at a certain height, a transverse rod group set on one side of the top of the longitudinal support rod, and a clamping plate that is horizontally rotatably connected to the front end of the transverse rod group; the longitudinal support rod adjusts its height to drive the clamping plate to clamp the inner side of the door and window frame, and the transverse rod group is finely adjusted in the horizontal plane to drive the clamping plate to clamp the door and window frame and move it to the installation area. A lead screw is rotatably provided on one side of the clamping plate, and a rotating sleeve is connected to the external thread of the lead screw. The lower end of the rotating sleeve rotates horizontally on the transverse rod group. The clamping plate is pressed against the inner side of the door and window frame by adjusting the length of both ends of the lead screw on the rotating sleeve.

[0010] As a further improvement to this technical solution, the transverse rod assembly is composed of a telescopic rod and a rod sleeve arranged in an inner and outer manner. An adjustment rod is fixed horizontally and vertically on one side of the front end of the rod sleeve. The adjustment rod passes through the top side wall of the longitudinal support rod and is positioned by bolts at the top of the longitudinal support rod.

[0011] As a further improvement to this technical solution, a sleeve frame is fixedly provided on the inner side of the top rod of the support frame. A sliding groove is opened horizontally on the side wall of the sleeve frame. The sliding groove passes through the side wall of the top rod. Several limiting holes are opened at equal intervals on the side of the longitudinal support rod. The limiting holes are square holes and are adapted to insert limiting pins. The limiting pins pass through the sliding groove.

[0012] As a further improvement to this technical solution, one end of the lead screw is fitted with a bearing and the outer ring of the bearing is fixedly connected to the side wall of the clamping plate. The bottom surface of the rotating sleeve is vertically provided with a pin, and the top surface of the front end of the telescopic rod is provided with a concave hole. The pin is inserted into the concave hole and rotated by being limited by a pin.

[0013] As a further improvement to this technical solution, a slot is provided in the middle of the front side of the support frame, and an insertion hole is provided in the side wall of the inner lining rod of the armrest frame. One end of the tray frame is engaged with the slot, and the other end is fixed to the two insertion holes by a long rod.

[0014] As a further improvement to this technical solution, a support portion is provided on the top surface of the front end of the loader for supporting the telescopic rods to move horizontally to the front of the loader; the support portion includes a pair of support rod groups, a bidirectional threaded rod installed on the top surface of the front end of the loader, and two sliders threadedly connected to the bidirectional threaded rod; one end of the support rod group is engaged with the slider and positioned by a pin, and by rotating the bidirectional threaded rod, the two sliders are driven to move in opposite directions along their axial direction, thereby adjusting the spacing of the pair of support rod groups to match the horizontal movement distance of the pair of telescopic rods.

[0015] As a further improvement to this technical solution, the support rod assembly consists of an adjusting rod and a rotating tube arranged in an inner and outer sleeve, and the extension length is positioned by bolts. The lower end side wall of the rotating tube has a through hole with a diameter larger than the outer diameter of the bidirectional threaded rod. The middle part of the slider has a notch with a threaded hole on the side wall of the notch.

[0016] As a further improvement to this technical solution, a positioning hole is provided on the lower side wall of the rotating tube. The positioning hole and the through hole on the side wall of the rotating tube are on the same central axis. The direction of the line connecting the center of the positioning hole and the through hole on the side wall of the rotating tube is consistent with the length direction of the rotating tube. A pin passes through the side wall of the slider and is inserted into the positioning hole.

[0017] As a further improvement to this technical solution, a groove is provided at the top center of the adjusting rod, the end face of the telescopic rod is T-shaped and its vertical section is engaged and slidably connected with the groove, and two rows of rollers are provided at the top of the adjusting rod and on both sides of the groove.

[0018] The present invention also provides a fixing method for an auxiliary fixing device for installing energy-saving door and window frames, comprising the following steps:

[0019] S1. Place several door frames against the loading vehicle, adjust the height of the clamping part and the support part according to the height of the door frame, so that a pair of clamping plates are clamped in the upper middle part of the door frame, and slide the telescopic rod and the adjusting rod to drive the door frame to extend outward to the installation area.

[0020] S2. Move the longitudinal support rod to the front of the door frame, rotate the clamping plate horizontally to the inside of the door frame, and quickly adjust the clamping plate to contact the inside of the door frame by first moving the telescopic rod towards the inside of the door frame, and then rotate the screw to finely adjust the clamping plate to press the door frame away from the bottom of the vehicle.

[0021] S3. Next, move the longitudinal support rod forward to the rear of the support part, move a pair of telescopic rods forward to move the door frame into the installation area while it is suspended in the air, drill holes in the wall frame according to the mounting holes on the side of the door frame, and fix the door frame with expansion bolts; during this period, the telescopic rod and the adjusting rod slide and engage to obtain support;

[0022] S4. After the door frame is fixed on the side, remove the clamping plate and then push the loader to the next installation area to repeat steps S2-S3 for installation.

[0023] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0024] 1. The installation auxiliary fixing device and fixing method for this energy-saving door and window frame, through the setting of the loading vehicle and the clamping part, realizes the mechanized handling and translation positioning of the door and window frame, replacing the traditional manual lifting and handling method, which is especially suitable for centralized installation scenarios; through the cooperative setting of the longitudinal support rod, the transverse rod group and the clamping plate in the clamping part, multiple adjustments to the height and width of the door and window frame are realized, and the clamping method of the middle upper part of the clamping plate avoids the problem of the door and window frame tipping over due to the top-heavy nature, thus improving the stability of handling.

[0025] 2. The installation auxiliary fixing device and fixing method of this energy-saving door and window frame, through the fine adjustment structure of the screw and the rotating sleeve, enables the clamping plate to quickly approach and press against the inside of the door and window frame, achieving a gentle yet firm clamping. In conjunction with the rubber pad, it protects the surface of the door and window frame and prevents scratches or damage during transportation.

[0026] 3. The installation auxiliary fixing device and fixing method of the energy-saving door and window frame, through the setting of the support part and the bidirectional threaded rod adjustment mechanism, allows the spacing and height of a pair of support rods to be flexibly adjusted, providing stable sliding support for the telescopic rod, ensuring that the door and window frame remains balanced during the translation process, avoiding bending or shaking due to excessive overhang, and improving the safety of translation.

Furthermore, in the description of the invention, "a number" means two or more, unless otherwise explicitly specified.

[0041] Please see Figures 1-4As shown, the present invention provides an auxiliary fixing device for the installation of energy-saving door and window frames, including a loading vehicle 100 for placing door and window frames and clamping parts 200 symmetrically arranged above the loading vehicle 100 for clamping door and window frames of different widths and moving them to the installation area; thereby reducing the workload of workers lifting door and window frames when installing door and window frames in a building, and improving work efficiency.

[0042] Furthermore, symmetrically fixed square-framed support frames 110 are provided on the left and right sides of the loading vehicle 100, which are fixed by welding or bolts, and will not be described in detail here; a rear-leaning backrest 120 is fixedly provided at the rear of the loading vehicle 100 so that the door and window frames do not tilt outwards when they are moved; when a pallet frame 130 is placed on the top surface of the loading vehicle 100, it is used to support the door frame, and when a pallet frame 130 is placed in the middle area in front of the backrest 120, it is used to support the window frame.

[0043] A slot 121 is provided in the middle of the front side of the support frame 120, and an insertion hole 113 is provided in the side wall of the inner lining rod of the support frame 110. One end of the pallet frame 130 is engaged with the slot 121, and the other end is fixed by a long rod through the two insertion holes 113 to stabilize the pallet frame 130. Limiting sleeves 122 are symmetrically fixed on the left and right sides of the top surface of the loading vehicle 100. When the pallet frame 130 is placed on the top surface of the loading vehicle 100, the long rod through the other end is engaged with a pair of limiting sleeves 122 for positioning. This facilitates the easy switching of the position of the pallet frame 130 to adapt to door and window frames of different heights. A baffle 131 is provided vertically at the front end of the pallet frame 130 to limit the door and window frames.

[0044] like Figures 5-6 As shown, the clamping part 200 slides back and forth along the top rod of the support frame 110 to transfer the door and window frame inside the loading vehicle 100; the clamping part 200 includes a longitudinal support rod 210 that slides on the top rod of the support frame 110 and is positioned at a certain height, a transverse rod group 220 set on one side of the top of the longitudinal support rod 210, and a clamping plate 230 that is horizontally rotatably connected to the front end of the transverse rod group 220; the longitudinal support rod 210 drives the clamping plate 230 to clamp the inner side of the door and window frame by adjusting its height, and the transverse rod group 220 is finely adjusted back and forth and left and right on the horizontal plane, thereby driving the clamping plate 230 to clamp the door and window frame and move it to the installation area. A lead screw 231 is rotatably provided on one side of the clamping plate 230, and a rotating sleeve 232 is threadedly connected to the outside of the lead screw 231. The lower end of the rotating sleeve 232 rotates horizontally on the transverse rod group 220. By adjusting the length of both ends of the lead screw 231 on the rotating sleeve 232, the clamping plate 230 is controlled to press the inner side of the door and window frame.

[0045] Furthermore, the transverse rod assembly 220 is composed of an inner and outer sleeve of a telescopic rod 221 and a sleeve 222. An adjustment rod 223 is fixed horizontally and vertically on one side of the front end of the sleeve 222. The adjustment rod 223 passes through the top side wall of the longitudinal support rod 210 and is positioned by bolts at the top of the longitudinal support rod 210. The distance between the transverse rod assembly 220 and the longitudinal support rod 210 is adjusted by moving the adjustment rod 223, thereby adapting to the width of the door and window frame for clamping preparation.

[0046] Furthermore, a sleeve frame 111 is fixedly provided on the inner side of the top rod of the support frame 110. The side wall of the sleeve frame 111 is provided with a horizontally oriented sliding groove 112, which penetrates the side wall of the top rod. The side of the longitudinal support rod 210 is provided with several equally spaced limiting holes 211. The limiting holes 211 are square holes and are adapted to be inserted with limiting pins 240. The limiting pins 240 pass through the sliding groove 112. This allows the longitudinal support rod 210 to be adjusted in height, and its height is limited by the limiting pins 240 being inserted into the limiting holes 211 at different positions. This supports the transverse rod assembly 220 and clamps it to the upper part of the middle of the door and window frame, preventing the door and window frame from tipping over due to its top-heavy design and reducing clamping pressure.

[0047] Furthermore, rubber pads are adhered to the sides of the clamping plate 230 to increase clamping friction and prevent wear on the door and window frames; a bearing is fitted at one end of the lead screw 231 and the outer ring of the bearing is fixedly connected to the side wall of the clamping plate 230, so that when the rotating lead screw 231 and the rotating sleeve 232 move together, the clamping plate 230 keeps the door and window frames clamped and does not rotate; a vertical insert is provided on the bottom surface of the rotating sleeve 232, and a recessed hole 2211 is opened on the top surface of the front end of the telescopic rod 221. The insert is inserted into the recessed hole 2211 and the rotation is limited by a pin; an annular groove is opened on the side wall of the bottom end of the insert, and the pin passes through the side wall of the telescopic rod 221 to the recessed hole 2211 and is inserted into the annular groove to limit the rotation of the rotating sleeve 232.

[0048] like Figure 7 As shown, a support portion 300 is provided on the top surface of the front end of the loader 100 for supporting the telescopic rod 221 to move to the front of the loader 100. The support portion 300 includes a pair of support rod assemblies 310, a bidirectional threaded rod 320 installed on the top surface of the front end of the loader 100, and two sliders 330 threadedly connected to the bidirectional threaded rod 320. One end of the support rod assembly 310 is engaged with the slider 330 and positioned by a pin. By rotating the bidirectional threaded rod 320, the two sliders 330 are driven to move in opposite directions along their axial direction, thereby adjusting the spacing of the pair of support rod assemblies 310 to match the translational distance of the pair of telescopic rods 221.

[0049] The support rod assembly 310 consists of an adjusting rod 312 and a rotating tube 311 arranged in an inner and outer sleeve. The length is adjusted by bolt positioning to match the height of the transverse rod assembly 220, thus providing support. The lower end side wall of the rotating tube 311 has a through hole with a diameter larger than the outer diameter of the bidirectional threaded rod 320, so that the rotating tube 311 can be sleeved with the bidirectional threaded rod 320 without being affected by it. The slider 330 has a notch in the middle and a threaded hole on the side wall of the notch for threaded connection with the bidirectional threaded rod 320.

[0050] Furthermore, a positioning hole 3111 is provided on the lower side wall of the rotating tube 311. The positioning hole 3111 and the through hole on the side wall of the rotating tube 311 are on the same central axis. The direction of the line connecting the center of the positioning hole 3111 and the through hole on the side wall of the rotating tube 311 is consistent with the length direction of the rotating tube 311. A pin passes through the side wall of the slider 330 and is inserted into the positioning hole 3111. This allows the support rod assembly 310 to rotate to a horizontal position and be stored. When erected, it is stably supported by the pin.

[0051] Furthermore, a groove 3121 is provided at the center of the top of the adjusting rod 312. The end face of the telescopic rod 221 is T-shaped and its vertical section is engaged and slidably connected with the groove 3121. The bottom center line of the rod sleeve 222 is open and is adapted to be engaged and slidably connected with the vertical section of the telescopic rod 221. This structure of the telescopic rod 221 helps to increase its bending resistance and better support the door and window frame. The engagement between the vertical section of the telescopic rod 221 and the groove 3121 also serves as a guide, making the lateral movement of the door and window frame stable. Two rows of rollers 313 are provided at the top of the adjusting rod 312 and on both sides of the groove 3121. These rollers 313 roll in contact with the top two sides of the vertical section of the telescopic rod 221, reducing the friction of the contact and making the telescopic rod 221 move smoothly.

[0052] The energy-saving door and window frame installation auxiliary fixing device of the present invention includes the following steps when installing the door frame:

[0053] S1. Place several door frames against the loading vehicle 100, adjust the height of the clamping part 200 and the support part 300 according to the height of the door frame, so that a pair of clamping plates 230 are clamped in the upper middle part of the door frame, and the telescopic rod 221 and the adjusting rod 312 are slidably connected to drive the door frame to extend outward to the installation area.

[0054] S2. Move the longitudinal support rod 210 to the front door frame, rotate the clamping plate 230 horizontally to the inside of the door frame, and quickly adjust the clamping plate 230 to contact the inside of the door frame by first moving the telescopic rod 221 to the inside of the door frame, and then rotate the screw 231 to finely adjust the clamping plate 230 to press the door frame away from the bottom of the vehicle.

[0055] S3. Next, move the longitudinal support rod 210 forward to the rear of the support part 300, move a pair of telescopic rods 221 forward to move the door frame suspended in the air toward the installation area, and then slowly release the clamping plate 230 to let the door frame fall onto the ground of the installation area. Then, drill holes in the wall frame according to the mounting holes on the side of the door frame, and fix the door frame with expansion bolts. During this period, the telescopic rod 221 and the adjusting rod 312 slide and engage to obtain support.

[0056] S4. After the door frame is fixed on the side, remove the clamping plate 230, and then push the loader 100 to the next installation area and repeat steps S2-S3 for installation.

[0057] Furthermore, when it is necessary to install the window frame, the support plate 130 is raised to the middle of the backrest 120 so that the middle of the window frame is placed within the clamping range of the clamping part 200, and then the installation is carried out according to steps S2-S3.

[0058] It should be noted that the fixed connection and fixing method of the present invention are achieved by conventional fixing means such as bolt connection, welding, or bonding that are compatible with each other. These are existing technologies and will not be described in detail here. The above embodiments are only for illustrating the technical concept and features of the present invention, and their purpose is to enable those skilled in the art to understand the content of the present invention and implement it accordingly. They should not be used to limit the scope of protection of the present invention. All equivalent changes or modifications made according to the spirit and essence of the present invention should be covered within the scope of protection of the present invention.
