Description

Technical Field

[0001] The invention belongs to the technical field of door-type frame construction, and specifically relates to a door-type frame that is easy to construct. Background Art

[0002] In some venues with a specific range but no enclosed buildings, it is often necessary to build a door-type frame and add a logo on it to serve as a gate to enter the venue, such as weddings and funerals, night market snack streets or construction sites, etc. This door-type frame is generally composed of columns on both sides and a beam frame on the top. In the prior art, there are two ways to assemble these door-type frames: one is to first erect the columns on both sides, and then use handling equipment or manual labor to lift the beam frame and hang it. This installation method has poor accuracy. After the beam frame is transported to the top of the column, it is still necessary to align it; the other is to first erect the columns on both sides, and then hang the beam frame at the lower limit position, and then use handling equipment or manual labor to pull the beam frame to the upper limit position. This method requires advance preparation and is very inconvenient to assemble. Both methods require the use of manpower or additional lifting equipment, such as elevators, belt conveyors, electric hoists, or simply cranes. If lifting equipment is used, the beam frame needs to be hoisted, which is very inconvenient to install and occupies a large space. If a traditional climber is used, it is necessary to install additional conduits or rails on the columns, and it needs to be disassembled after installation, which is not only time-consuming and labor-intensive but also increases the installation cost. Therefore, it is necessary to design an electric door frame that does not require additional handling equipment. Utility Model Content

[0003] The utility model aims to provide a door-type frame which is easy to build and does not require additional handling equipment, and aims to solve the problems of primitive and low efficiency of traditional door-type frame building methods in the prior art.

[0004] In order to solve the above problems, the utility model adopts the following technical solutions:

[0005] An easy-to-build door-shaped frame comprises two columns arranged relatively parallel to each other;

[0006] Lifting frames, there are two lifting frames, which correspond to the opposite inner sides of the two columns one by one and are slidably connected along the vertical direction thereof;

[0007] A beam frame, both ends of which are detachably connected to the two lifting frames;

[0008] A driving part, wherein a fixed end of the driving part is fixedly connected to the beam frame;

[0009] The transmission part includes a transmission sprocket and a fixed chain. The transmission sprocket is in transmission connection with the driving end of the driving part. The fixed chain is parallelly assembled on the inner side of the column corresponding to one side of the lifting frame. The transmission sprocket is meshed with the fixed chain to drive the beam frame to rise and fall.

[0010] The beneficial effect of the utility model is that by arranging a fixed chain in the vertical direction on the column, and then cooperating with the transmission sprocket and the driving part on the beam frame, the kinetic energy output by the driving part is converted into the rotational motion of the transmission sprocket, and the transmission sprocket is driven to move along the fixed chain, thereby successfully driving the beam frame to rise and fall along the column. Since the driving part of the utility model is installed on the beam frame and the column is equipped with a fixed chain for lifting, there is no need to introduce additional lifting equipment. The transmission is stable and the installation is very simple. In particular, when installing the fixed chain on the column, it is only necessary to arrange the fixed chain between the upper and lower inner sides of the column close to the beam frame and tighten it. It is easy to install and occupies little space.

[0011] Furthermore, it also includes a mounting plate and a transmission shaft, wherein the mounting plate is fixedly connected to the end of the beam frame; the transmission shaft passes through the mounting plate and is rotationally connected thereto, the transmission shaft is transmission-connected to the driving end of the driving part, and one end of the transmission shaft is connected to the transmission sprocket.

[0012] A further beneficial effect of the present invention is that, by providing a mounting plate at the end of the beam frame, the transmission sprocket is rotatably connected to the mounting plate and is transmission-connected to the driving end of the driving part through the transmission shaft. After the beam frame is docked with the lifting frame, the transmission sprocket can better engage with the fixed chain.

[0013] Furthermore, it also includes a chain stabilizing wheel, which is arranged on both sides of the fixed chain in parallel with the horizontal direction of the axis of the transmission sprocket, and the chain stabilizing wheel is movably mounted on the mounting plate. The distance between the chain stabilizing wheel and the transmission sprocket is adjustable, and the chain stabilizing wheel can engage with the fixed chain.

[0014] A further beneficial effect of the utility model is that a chain stabilizing wheel is arranged on the other side of the fixed chain and assembled on the mounting plate, and the chain is clamped between the chain stabilizing wheel and the transmission sprocket by adjusting the distance between the chain stabilizing wheel and the transmission sprocket, so that both sides of the fixed chain are subjected to force at the same time, which is more stable than single-sided engagement with the transmission sprocket, and the clamping effect between the chain stabilizing wheel and the transmission sprocket can also have the effect of tensioning the fixed chain.

[0015] Furthermore, it also includes a stabilizing wheel adjusting block for adjusting the horizontal spacing between the transmission sprocket and the chain stabilizing wheel, one end of the stabilizing wheel adjusting block is rotatably connected to the transmission shaft or the mounting plate, and the chain stabilizing wheel is rotatably connected to the stabilizing wheel adjusting block via a connecting shaft; an operating rod, one end of the operating rod is movably connected to the stabilizing wheel adjusting block to drive the stabilizing wheel adjusting block to rotate and thereby change the horizontal spacing between the chain stabilizing wheel and the transmission sprocket.

[0016] A further beneficial effect of the utility model is that a stabilizing wheel adjusting block is provided to movably mount the chain stabilizing wheel on the mounting plate. Since the position of the transmission sprocket on the mounting plate remains unchanged, the position of the chain stabilizing wheel on the mounting plate can be changed by driving the stabilizing wheel adjusting block to rotate through the operating lever, thereby adjusting the horizontal spacing between the chain stabilizing wheel and the transmission sprocket and forming a height difference. During this process, the chain stabilizing wheel continuously approaches the transmission sprocket and finally cooperates with the transmission sprocket to mesh and clamp the fixed chain from both sides of the fixed chain, thereby forming a more stable connection relationship between the transmission sprocket and the fixed chain and preventing the beam frame from shaking during the lifting process. At the same time, since the height difference can be caused to form between the chain stabilizing wheel and the transmission sprocket in the process of rotating the stabilizing wheel adjusting block, it can additionally play a role in tensioning the fixed chain when the fixed chain is finally clamped.

[0017] Furthermore, the beam frame is provided with a long guide hole arranged along the direction of the fixed chain, and operating end locking grooves of an operating rod are provided at both ends corresponding to the long guide hole. The rod body of the operating rod passes through the long guide hole, and its operating end can drive its movable connection end to rotate and be positioned and locked through the locking groove of the operating end.

[0018] A further beneficial effect of the present invention is that the guide long hole is provided to guide the operating rod, regulate the movement trajectory of the operating rod, prevent the operating rod from being offset during movement and affect the normal clamping and fixing of the chain between the chain stabilizing wheel and the transmission sprocket, and utilize the operating end locking grooves extending from both ends of the guide long hole to provide a locking effect. When the operating end of the operating rod is pressed down to the bottom end of the guide long hole, the operating rod is rotated horizontally to move the operating rod into the operating end locking groove, so that the operating rod can be locked to maintain it in the current state, and the chain stabilizing wheel can be prevented from being separated from the fixed chain due to accidental touch.

[0019] Further, the lifting frame comprises:

[0020] A slide plate, wherein the slide plate is slidably connected to the column;

[0021] A card plate, the card plate is vertically fixed to the upper part of the skateboard surface;

[0022] A support plate, the support plate being vertically fixed to the lower end of the skateboard surface;

[0023] The end of the beam frame is connected to the clamping plate, and the lower end surface is connected to the supporting plate by clamping.

[0024] A further beneficial effect of the utility model is that the structure of the lifting frame is specifically disclosed, the slide plate is the main body, and slides up and down along the column, and the clamping plate and the support plate cause the beam frame to be connected with the slide plate, so that the beam frame can move up and down along the column.

[0025] Furthermore, the support plate includes a horizontal support plate and a vertical baffle plate, one end of the horizontal support plate is vertically fixedly connected to the lower end of the skateboard surface, and the vertical baffle plate is vertically fixedly connected to the other end of the horizontal support plate upward.

[0026] A further beneficial effect of the utility model is that the structure of the support plate is specifically disclosed, the horizontal support plate can abut the bottom end of the beam frame so that the beam frame is placed on the horizontal support plate, the vertical baffle plate can extend into the beam frame to prevent the beam frame from sliding off the horizontal support plate, and the horizontal support plate and the vertical baffle plate cooperate with each other to ensure that the lower end of the beam frame is stably connected to the lifting frame.

[0027] Furthermore, it also includes a card board connecting plate, the card board's card opening is arranged upward, the card board connecting plate is fixedly connected to the end of the beam frame, and its plate surface is provided with a hanging hole corresponding to the card board, and the card board connecting plate can be detachably hung on the card board's card opening through the hanging hole.

[0028] A further beneficial effect of the utility model is that the end of the beam frame is connected to the clamping plate through the clamping plate connecting plate, so that the beam frame and the lifting frame are docked, and the support plate abuts against the lower end of the beam frame to support the beam frame.

[0029] Furthermore, it also includes a cardboard anti-drop-off plate, one end of which is rotatably connected to the beam frame, and the other end has an anti-drop-off hook which can be rotated to the lower end of the cardboard bayonet to resist the cardboard.

[0030] A further beneficial effect of the utility model is that, by designing the card board anti-drop plate, the stability between the card board connecting plate and the card board is further guaranteed, and the card board is prevented from being decoupled.

[0031] Furthermore, the driving part is an electric motor, and the casing of the electric motor is fixedly connected to the beam frame; the transmission shaft is horizontally arranged in the beam frame, and its two ends are flush with the two ends of the beam frame, the shaft body of the transmission shaft is transmission-connected to the output end of the motor, and there are two transmission sprockets, which are respectively fixed on the ends of the transmission shaft.

[0047] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments in the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0048] As shown in the accompanying drawings, the utility model provides a door-shaped frame that is easy to build, which is mainly composed of the following parts: first, there are two columns 1, which eventually form the pillars of the door-shaped frame, and second, the beams 3, which eventually form the arch of the door-shaped frame. In this embodiment, the columns 1 and the beams 3 are both truss structures, and are both rectangular, formed by welding multiple square tubes.

[0049] Next is the lifting frame 2. There are also two lifting frames 2, each corresponding to a column 1. The two ends of each lifting frame 2 are slidably connected to the vertical square tubes on the opposite inner sides of the two columns 1. The lifting frames 2 on the two columns 1 are respectively used to support one end of the beam frame 3, which is the basis for the beam frame 3 to move up and down along the column 1, ensuring a stable installation relationship between the beam frame 3 and the column 1.

[0050] Finally, there are the driving part 4 and the transmission part 5 , which are the basis for the utility model to achieve lifting. The driving part 4 is electrically driven and installed inside the beam frame 3 .

[0051] The transmission part 5 mainly includes a transmission sprocket 501 and a fixed chain 502. The transmission sprocket 501 is connected to the output end of the driving part 4 by transmission. The fixed chain 502 is installed on the inner side of the column 1. Specifically, holes are opened on the upper and lower square tubes on the inner side of the column 1, and the fixed chain 502 is arranged vertically. The two ends pass through the holes on the square tubes and are fixed, so that the fixed chain 502 is in a tensioned state. The transmission sprocket 501 is arranged at both ends of the beam frame 3. When the beam frame 3 and the lifting frame 2 are installed, the transmission sprocket 501 meshes with the fixed chain 502. When the driving part 4 is started, Afterwards, the transmission sprocket 501 rotates and climbs along the fixed chain 502, and with the cooperation of the lifting frame 2, the lifting of the beam frame 3 is finally realized. The driving part 4 and the transmission sprocket 501 of the utility model are built in the beam frame 3 and matched with the fixed chain 502 installed on the column 1. Therefore, there is no need to introduce additional lifting equipment, the transmission is stable and the installation is very simple, especially when the fixed chain 502 is arranged on the column 1, because the column 1 adopts a truss structure, it is only necessary to arrange the fixed chain 502 between the upper and lower square tubes on the opposite inner sides of the column 1 and tighten it.

[0052] To further improve the technical solution, the utility model also includes a mounting plate 303 and a transmission shaft 503. The mounting plate 303 is located at the end of the beam 3 and is welded or bolted to the beam 3. The transmission shaft 503 is located in the beam and is arranged horizontally. Its two ends are flush with the two ends of the beam 3, the middle is transmission-connected to the output end of the drive unit, and the end is docked with the transmission sprocket 501. The two ends being flush with the two ends of the beam 3 here means that the length of the transmission shaft 503 can meet the position requirement of the transmission sprocket 501 at the end of the beam 3, ensuring that the transmission sprocket 501 can smoothly engage the fixed chain 502 after the beam 3 is docked with the lifting frame 2. In this embodiment, the beam 3 is rectangular, so the length of the transmission shaft 503 is approximately equal to the length of the beam 3. If the beam 3 is arched, the length of the transmission shaft 503 is approximately equal to the chord length corresponding to the beam 3. Through the cooperation between the mounting plate 303 and the transmission 503 , after the beam frame 3 is docked with the lifting frame 2 , the transmission sprocket 501 can be easily engaged with the fixed chain 502 .

[0053] To further improve the technical solution, the utility model also includes a chain stabilizing wheel 602, which is parallel to the horizontal direction of the axis of the transmission sprocket 501 and is relatively arranged on both sides of the fixed chain 502. The chain stabilizing wheel 602 is movably assembled on the mounting plate 303, so the distance between the chain stabilizing wheel 602 and the transmission sprocket 501 is adjustable. In the process of adjusting the distance between the chain stabilizing wheel 602 and the transmission sprocket 501, the chain stabilizing wheel 602 can gradually engage with the fixed chain 502 and cooperate with the transmission sprocket 501 to clamp the fixed chain 502.

[0054] In order to further improve the technical solution, the utility model also includes a stabilizing wheel adjusting block 601 for adjusting the distance between the chain stabilizing wheel 602 and the transmission sprocket 501. The stabilizing wheel adjusting block 601 is a shell, which is also rotatably connected to the mounting plate 303 and can also be rotatably connected to the transmission shaft 503; the chain stabilizing wheel 602 is rotatably connected to the stabilizing wheel adjusting block 601 through a connecting shaft, and the chain stabilizing wheel 602 and the transmission sprocket 501 are on the same side of the stabilizing wheel adjusting block 601, both facing the fixed chain 502. The fixed chain 502 is located between the transmission sprocket 501 and the chain stabilizing wheel 602. The operating rod 603 is specifically installed on the housing of the stabilizing wheel adjusting block 601, and is located at one end close to the chain stabilizing wheel 602. By pressing down the operating rod 603, the end of the stabilizing wheel adjusting block 601 with the chain stabilizing wheel 602 can be rotated. When the beam frame 3 is docked with the lifting frame 2, the transmission sprocket 501 and the chain stabilizing wheel 602 are initially located in the same horizontal plane, parallel and spaced apart, and the gap between the two The fixed chain 502 is in the middle, and the fixed chain 502 is first meshed with the driving sprocket 501, and then the operating lever 603 is operated to rotate the stabilizing wheel adjusting block 601 downward. In this process, the distance between the driving sprocket 501 and the chain stabilizing wheel 602 in the horizontal direction is gradually reduced until the chain stabilizing wheel 602 and the driving sprocket 501 clamp the fixed chain 502. At this time, a height difference is formed between the chain stabilizing wheel 602 and the driving sprocket 501. The utility model provides a very convenient operation method through the above design, which can reduce the horizontal distance between the driving sprocket 501 and the chain stabilizing wheel 602 by adjusting the position between the driving sprocket 601 and the chain stabilizing wheel 602, not only can the fixed chain 502 be meshed, but also a more stable connection relationship can be formed between the driving sprocket 501 and the fixed chain 502, so as to prevent the beam frame 3 from shaking during the lifting process. At the same time, the height difference between the chain stabilizing wheel 602 and the driving sprocket 501 can also play a tensioning role on the fixed chain 502.

[0055] In order to further improve the technical solution, the utility model also provides a long strip-shaped guide hole 604 on the beam frame 3, and a smaller operating end locking groove 605 is separately opened on the two ends of the guide hole 604 to the side. Specifically, the stabilizing wheel adjustment block 601 is located at the end of the beam frame 3, and its two sides are respectively two vertical square tubes at the end of the beam frame 3, one of which corresponds to one end of the stabilizing wheel adjustment block 601 on which the operating rod 603 is installed, and a long strip-shaped guide hole 604 is provided on the square tube. The width of the guide hole 604 is adapted to the diameter of the operating rod 603, and its main purpose is to guide the operating rod 603 and standardize the moving trajectory of the operating rod 603. The operating rod 603 is prevented from being offset during movement and affecting the normal clamping of the fixed chain 502 between the chain stabilizing wheel 602 and the transmission sprocket 501. The operating rod 603 is movably connected to the stabilizing wheel adjusting block 601 through a pin shaft or a universal shaft and other structures, and can be rotated in the horizontal direction. When the operating rod 603 is pressed down to the bottom of the guide long hole 604, the operating rod 603 can be rotated and moved sideways into the operating end locking groove 605, which is similar to the gear shifting operation of a car. The operating end locking groove 605 is used to prevent the operating rod 603 from rebounding, thereby maintaining the positional relationship between the transmission sprocket 501 and the chain stabilizing wheel 602, ensuring that the fixed chain 502 in the middle is always clamped during the lifting process.

[0056] Specifically, in the present invention, the lifting frame 2 includes: a slide plate 201, which is located on one side of the column 1 where the fixed chain 502 is arranged, and is also the main part of the entire lifting frame 2. The two sides are respectively slidably connected with two vertically arranged square tubes on the side of the column. The sliding connection method is not limited. A common method is to set U-shaped grooves on both sides of the slide plate 201 and buckle them on the square tubes, which will not be repeated here; a card plate 202, which is welded or bolted to the middle and upper end of the board surface of the slide plate 201, and a card plate connecting plate 301 is correspondingly arranged on the beam frame 3, and the card plate connecting plate 301 is located above the stabilizing wheel adjustment block 601 It is welded or bolted to the beam frame 3, and a hanging hole is opened on the board surface of the card connecting plate 301. The card plate 202 is hung on the card connecting plate 301 through the hanging hole, thereby prompting the skateboard 201 and the beam frame 3 to be docked; the support plate 203, the support plate 203 is welded or bolted to the lower end of the board surface of the skateboard 201, and the main purpose of the support plate 203 is to support the bottom. The support plate 203 is composed of a horizontal support plate 203-1 and a vertical baffle 203-2. One end of the horizontal support plate 203-1 is vertically welded to the lower end of the board surface of the skateboard 201, and the lower end of the vertical baffle 203-2 is vertically welded to the other end of the horizontal support plate 203-1.

[0057] In order to further improve the technical solution, the present invention is also provided with a card board anti-drop plate 302. The main function of the card board anti-drop plate 302 is to resist the card board 202 and prevent the card board 202 from detaching from the hanging hole. The form of the card board anti-drop plate 302 is not limited, as long as it can prevent the card board 202 from detaching from the hanging hole. In the present embodiment, the card board anti-drop plate 302 is located on the inner side of the card board connecting plate 301, and the upper end of the card board anti-drop plate 302 is mounted on the beam frame 3 through a torsion spring, and the lower end is provided with an anti-drop hook perpendicular to the board surface. Normally, the card board anti-drop plate 302 is pulled up. When the card board 202 enters the hanging hole, the card board anti-drop plate 302 is lowered. At this time, the anti-drop hook at the lower end of the card board anti-drop plate 302 can resist the card board 202 from below to prevent the card board 202 from detaching.

[0058] Specifically, the driving part 4 of the utility model is an electric motor 401, which is located in the beam frame 3. The housing of the electric motor 401 is bolted to the beam frame 3, and the output shaft and the middle part of the shaft body of the transmission shaft 503 are connected in a transmission manner. In addition, a series of structures such as a transmission sprocket 501 and a chain stabilizing wheel 602 can be set at both ends of the transmission shaft 503.

[0059] To further improve the technical solution, the utility model also includes a coupling 402. The motor 401 is installed in the middle of the beam 3, and the output shaft is vertically downward. The coupling 402 is located below the motor 401 and connected to the output shaft of the motor 401, and the motor 401 is also connected to the remote control electrical signal.

[0060] To further improve the technical solution, a bearing seat is bolted to one side of the mounting plate 303 close to the transmission shaft 503, and a bearing is rotatably connected inside the bearing seat. The stabilizing wheel adjustment block 601 is located on the other side of the mounting plate 303, and the end of the transmission shaft 503 passes through the bearing and the mounting plate 303 and is connected to the transmission shaft 503 for transmission.

[0061] The utility model uses the mounting plate 303 and the bearing to share the force applied to the transmission shaft 503 by the transmission sprocket 501 and the stabilizing wheel adjustment block 601 at both ends of the transmission shaft 503. Since the transmission shaft 503 is relatively long and the two sets of transmission sprockets 501 are distributed at both ends of the transmission shaft 503, under the influence of the deadweight of the transmission sprocket 501 and the stabilizing wheel adjustment block 601, the transmission shaft 503 may be deformed or slightly tilted downward at the end. In order to prevent the transmission shaft 503 from being deformed or displaced at the end, thereby affecting the alignment effect of the two ends of the beam frame 3 and the two columns 1, the utility model arranges the above-mentioned mounting plates 303 at both ends of the transmission shaft 503, and a bearing seat and a bearing inside the bearing seat are also fixed on the mounting plate 303. When the transmission shaft 503 passes through the bearing and the mounting plate 303 and then transmits and connects to the transmission sprocket 501, the mounting plate 303 and the bearing can provide an upward support force for the end of the transmission shaft 503 without affecting the normal rotation of the transmission shaft 503.

[0062] The above is the specific structure of the door-type frame provided by the utility model. Next, the specific construction steps of the electric door-type frame are introduced:

[0063] The first step is to erect two columns 1 and adjust the distance between the two columns 1 to match the length of the beam frame 3;

[0064] The second step is to overlap the two ends of the beam frame 3 on the support plate 203 respectively, and extend the clamping plate 202 into the hanging hole of the clamping plate connecting plate 301. The beam frame 3 and the lifting frame 2 are connected;

[0065] The third step is to lower the card plate anti-drop plate 302 to hold the card plate 202 against it to prevent it from falling out during movement;

[0066] Step 4: align the transmission sprocket 501, the chain stabilizing wheel 602 and the fixed chain 502 so that the fixed chain 502 is located between the transmission sprocket 501 and the chain stabilizing wheel 602;

[0067] Step 5: Press down the operating rod 603 to make the transmission sprocket 501 and the chain stabilizing wheel 602 mesh and clamp the fixed chain 502, and lock the operating rod 603;

[0068] Step 6: Start the motor 401 and use the remote control to make the beam 3 automatically rise upward;

[0069] Step 7: Complete the construction of the door frame.

[0070] Although the embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the claims and their equivalents.
