Description

Technical Field

[0001] This invention belongs to the field of energy storage equipment technology, specifically relating to a device for fixing and installing heating tubes for energy storage heating. Background Technology

[0002] Solar water heaters are common outdoor heat storage and energy supply devices. They consist of many thin-walled heating elements. When sunlight shines on these elements, they absorb solar energy, become hot, and transfer the heat to the water inside. The water then heats up to become hot water. Heating elements come in various shapes. Traditional heating elements are straight pipes, which are simple to construct and easy to install. However, because the angle of sunlight is constantly changing, sunlight cannot always directly reach the pipe. In contrast, curved pipes can be installed according to the angle of sunlight to ensure that sunlight always reaches the pipe directly.

[0003] During the installation of the arc-shaped heating element, the pipe is usually inserted into the water tank interface by hand. This process requires a high level of installation skill from the operator. Even a slight deviation in the installation angle may cause the pipe end to rub against the water tank interface, thus affecting the sealing performance of the pipe opening. In addition, because the pipe wall is relatively thin, the pressure on the part of the pipe in contact with the person's hand is very large when the pipe is pressed down by hand, which can easily cause the pipe wall to deform. Summary of the Invention

[0004] To solve the above technical problems, the present invention adopts the following technical solution: a heating tube fixing and installation device for energy storage heating, including a horizontal processing table, a guide rail arranged in the front-to-back direction fixedly installed on the processing table, a sliding seat horizontally slidably installed on the processing table via the guide rail, grooves being provided on the surface of the sliding seat near its front and rear ends, and stops corresponding to the positions of the sliding seat being installed at both ends of the guide rail, four clamping blocks being slidably installed on the upper surface of the sliding seat, and first racks arranged in the front-to-back direction being fixedly installed on the left and right side walls of the sliding seat, and a drive motor being fixedly installed on the processing table at the position corresponding to the first rack via a motor table, a vertical shaft being fixedly installed on the output end of the drive motor, and a first missing gear meshing with the first rack being fixedly installed on the vertical shaft.

[0005] A docking mechanism is installed on the processing table. The docking mechanism includes a gantry frame that is fixedly installed on the processing table by a bracket. Several docking cylinders are vertically fixed on the crossbeam of the gantry frame. An arc-shaped frame is fixedly installed at the bottom of the telescopic section of the several docking cylinders. The axis of the arc-shaped frame is arranged in the front-back direction. An arc-shaped groove that coincides with its axis is opened on the front end face of the arc-shaped frame. The surface of the arc-shaped groove matches the surface of the heating tube.

[0006] Limiting mechanisms are installed on both the left and right side walls of the processing table. The limiting mechanism includes a support platform fixedly installed on the side wall of the processing table. An inverted L-shaped frame is fixedly installed on the support platform. A limiting rod that passes through the L-shaped frame is movably installed on the horizontal section of the L-shaped frame. An end plate is fixedly installed at the top of the limiting rod. A limiting spring sleeved on the limiting rod is fixedly connected between the end plate and the L-shaped frame.

[0007] As a preferred embodiment of the present invention, a limiting strip penetrating the L-shaped frame is vertically fixedly installed on the limiting rod, a connecting rod is fixedly installed on the end plate, and a guide rod is vertically fixedly installed at the end of the connecting rod; a horizontal plate is fixedly installed at the top of the vertical shaft, and an annular guide plate corresponding to the position of the guide rod is fixedly installed on the horizontal plate.

[0008] As a preferred embodiment of the present invention, a ball is installed at the bottom end of the guide rod and fits against the top surface of the annular guide plate. The annular guide plate is composed of a first arc segment and a second arc segment. The top surfaces of the first arc segment and the second arc segment are horizontal. The connection point on one side of the first arc segment and the second arc segment is a vertical surface, and the connection point on the other side of the first arc segment and the second arc segment is an inclined surface.

[0009] As a preferred embodiment of the present invention, the sliding seat and the guide rail are fitted with an inverted groove with the opening facing downwards, and several balls that fit against the guide rail are evenly installed on each plane of the inverted groove; the bottom end face of the limiting rod is a hemispherical surface.

[0010] As a preferred embodiment of the present invention, two baffles with through arc-shaped grooves are slidably installed on the surface of the arc-shaped frame along its radial direction, and vertical plates are fixedly installed on the crossbeam of the portal frame corresponding to the position of each baffle; a round rod with a horizontal through-the-baffle is rotatably installed at the top of the baffle, and a guide groove that cooperates with the round rod is opened on the vertical plate; the guide groove is C-shaped and the guide groove bends toward the middle of the arc-shaped frame.

[0011] As a preferred embodiment of the present invention, an inclined top plate is fixedly installed on the top of the baffle, and an elastic telescopic rod is fixedly installed on the arc frame at the position corresponding to each top plate, with the top end of the telescopic section of the elastic telescopic rod fixedly connected to the top plate.

[0012] As a preferred embodiment of the present invention, a positioning plate that penetrates the portal frame column is horizontally slidably installed on the column of the portal frame. The upper surface of the positioning plate is horizontal. A movable plate is fixedly installed at the end of the positioning plate away from the arc frame. A horizontal return spring is fixedly connected between the movable plate and the corresponding portal frame column.

[0013] As a preferred embodiment of the present invention, a second rack arranged in the left-right direction is fixedly installed on the upper surface of the positioning plate, and a positioning motor is fixedly installed on the column of the portal frame through a motor base. A second missing gear that meshes with the second rack is fixedly installed on the output shaft of the positioning motor.

[0014] The present invention has at least the following beneficial effects: (1) In the present invention, after the heating tube is manually placed on the arc frame of the docking mechanism, the baffle can automatically limit the pipe during the descent of the arc frame, so that the pipe is always in contact with the inner end surface of the arc groove, avoiding the pipe from shifting in the front and back directions. At the same time, the positioning plate positions the two ends of the pipe so that the two ends of the pipe can reach a level state. In summary, the docking mechanism can automatically adjust the pipe so that the pipe is in an accurate installation state. During the process of the docking cylinder driving the arc frame and the pipe in this state to continue to descend and be inserted into the water tank interface, the pipe can maintain the feed direction unchanged, thereby avoiding the situation where the pipe port scratches the water tank interface.

[0015] (2) The present invention uses the cooperation of the first rack and the first missing gear to drive the sliding seat and the water tank on the sliding seat to move intermittently in a directional manner. When the water tank is stationary (i.e., during the process of the heating tube being inserted into the water tank interface), the limiting mechanism limits the next interface to be inserted, so that the entire water tank remains stationary during the insertion process, which further improves the accuracy of the pipe port and the water tank interface. Since the connection accuracy requirements of the pipe port and the water tank interface are high, the cooperation of the first rack and the first missing gear cannot guarantee that the pipe port can be aligned with the water tank interface before each connection. When the limiting rod in the limiting mechanism is inserted into the water tank port, a certain force will be generated between it and the water tank port. Since the bottom of the limiting rod is a hemispherical surface and the friction between the guide rail and the sliding seat is small due to the presence of the ball, the limiting rod will push the water tank and the sliding seat to move a small distance so that the limiting rod can be inserted into the water tank interface, thereby further improving the accuracy of the pipe port and the water tank interface.

[0016] (3) In the process of the arc frame in the docking mechanism of the present invention driving the pipe to be inserted into the water tank interface, the entire surface of the arc groove is in contact with the pipe and applies pressure to the pipe, thereby reducing the local pressure on the pipe and avoiding deformation of the pipe wall; after the insertion is completed, the sliding seat drives the water tank and the pipe to move forward, and the pipe will not be subjected to squeezing force during the process of leaving the arc frame, thus avoiding pipe deformation.

[0028] The embodiments of the present invention will be described in detail below with reference to the accompanying drawings, but the present invention can be implemented in many different ways as defined and covered by the claims.

[0029] like Figure 1 , Figure 2 , Figure 4 and Figure 7As shown, this embodiment provides a heating element fixing and installation device for energy storage heating. This device is semi-automatic, requiring operator assistance for loading and unloading. The device includes a horizontal processing table 1, on which guide rails 2 arranged in a front-to-back direction are fixedly installed. A sliding seat 3 is horizontally slidably mounted on the processing table via the guide rails 2. Grooves 301 are formed on the surface of the sliding seat 3 near its front and rear ends. The mating point between the sliding seat 3 and the guide rail 2 is a downward-facing C-shaped groove 302. Several balls 303 are evenly installed on each plane of the C-shaped groove 302, which conform to the guide rail 2, to reduce the friction between the guide rail 2 and the sliding seat 3. Friction causes the sliding seat 3 to move when subjected to a small thrust along the front-back direction. Both ends of the guide rail 2 are equipped with stops 11 corresponding to the positions of the sliding seat 3. The front stop 11 is elastically telescopically engaged with the guide rail 2, and the rear stop 11 is fixedly connected to the guide rail 2. Four clamping blocks 4 are slidably installed on the upper surface of the sliding seat 3. The clamping blocks 4 are electrically controlled. The left and right side walls of the sliding seat 3 are fixedly installed with first racks 5 arranged along the front-back direction. The position of the first rack 5 on the processing table is fixedly installed with a drive motor 6 via a motor table. A vertical shaft 7 is fixedly installed on the output end of the drive motor 6. A first missing gear 8 that meshes with the first rack 5 is fixedly installed on the vertical shaft 7.

[0030] Before starting work, the operator pulls the groove 301 at the rear end to move the sliding seat 3 backward until the sliding seat 3 presses against the stop block 11 at the rear end. Then, the water tank is manually placed on the sliding seat 3, and the water tank is positioned and clamped by the clamping block 4. Then, the drive motor 6 is started, which drives the vertical shaft 7 and the first missing gear 8 to rotate continuously. The first missing gear 8 drives the first rack 5, which meshes with it, to move forward intermittently. During the movement of the first rack 5, the sliding seat 3 and the water tank located on the sliding seat 3 move synchronously. The distance that the first rack 5, the sliding seat 3 and the water tank move each time is constant.

[0031] like Figure 1 , Figure 3 , Figure 5 and Figure 8As shown, a docking mechanism 9 is installed on the processing table 1. The docking mechanism 9 is used to connect the pipe to the water tank. The docking mechanism 9 includes a portal frame 901 fixedly installed on the processing table 1 by a bracket. Several docking cylinders 902 are vertically fixedly installed on the crossbeam of the portal frame 901. The bottom ends of the telescopic sections of the several docking cylinders 902 are jointly fixedly installed with an arc-shaped frame 903. The axis of the arc-shaped frame 903 is arranged in the front-rear direction. The front end face of the arc-shaped frame 903 has a part that coincides with its axis. The arc-shaped groove 904 has a surface that mates with the surface of the heating element; two baffles 905 are slidably mounted radially on the surface of the arc-shaped frame 903, penetrating the arc-shaped groove 904; vertical plates 906 are fixedly mounted on the crossbeam of the portal frame 901 corresponding to the position of each baffle 905; a round rod 907 is rotatably mounted on the top of the baffle 905, penetrating the baffle 905; a guide groove 908 is provided on the vertical plate 906 to mate with the round rod 907; the guide groove 908 is... The C-shaped guide groove 908 bends towards the middle of the arc frame 903; an inclined top plate 909 is fixedly installed on the top of the baffle 905; an elastic telescopic rod 910 is fixedly installed on the arc frame 903 at the position corresponding to each top plate 909, and the top end of the telescopic section of the elastic telescopic rod 910 is fixedly connected to the top plate 909; a positioning plate 911 is horizontally slidably installed on the column of the portal frame 901, penetrating the column of the portal frame 901, and the upper surface of the positioning plate 911 is horizontal. A movable plate 912 is fixedly installed at the end of the positioning plate 911 away from the arc frame 903. A horizontal return spring 913 is fixedly connected between the movable plate 912 and the corresponding column of the portal frame 901. A second rack 914 arranged in the left-right direction is fixedly installed on the upper surface of the positioning plate 911. A positioning motor 915 is fixedly installed on the column of the portal frame 901 through a motor base. A second missing gear 916 that meshes with the second rack 914 is fixedly installed on the output shaft of the positioning motor 915.

[0032] With the first gear 8 disengaged from the first rack 5, i.e., the first rack 5, sliding seat 3, and water tank are stationary, a single pipe is manually placed into the arc groove 904 on the arc frame 903, and pushed so that the pipe fits against the inner end face of the arc groove 904. Then, the docking cylinder 902 drives the arc frame 903, pipe, baffle 905, round rod 907, top plate 909, and elastic telescopic rod 910 to move downwards simultaneously. In the initial state, the end face of the baffle 905 is flush with the surface of the arc groove 904. Since the round rod 907 is in a mating state with the guide groove 908, the round rod 907 will be in the guide groove 904 during its descent. Under the guidance of 8, horizontal displacement is generated. Driven by the round rod 907, the baffle 905 moves radially towards the center of the arc frame 903. The baffle 905 extends into the arc groove 904 to block the pipe, preventing forward and backward displacement during insertion. Before the pipe end is inserted into the water tank interface, the positioning motor 915 drives the second missing gear 916 to rotate. The second missing gear 916 drives the second rack 914, positioning plate 911, and moving plate 912 to move horizontally. The return spring 913 is compressed, and the end of the positioning plate 911 reaches below the pipe port. If the two ends of the pipe are not aligned, the lower end... The pipe ends will align with the corresponding positioning plate 911. As the pipe continues to descend, the positioning plate 911 will push the pipe to move circumferentially within the arc groove 904 until both ends of the pipe are aligned with the positioning plate 911, i.e., the two ends of the pipe reach a flush state. Subsequently, the second gear 916 separates from the second rack 914, and the return force of the return spring 913 causes the second rack 914, positioning plate 911, and moving plate 912 to quickly return to their original positions to prevent the positioning plate 911 from obstructing the pipe descent process. After the pipe end is inserted into the water tank interface, the arc frame 903, pipe, baffle 905, round rod 907, and elastic telescopic rod 910 continue to descend. Driven by the round rod 907, the baffle 905 moves and resets radially away from the center of the arc frame 903. The baffle 905 no longer limits the pipe, thus ensuring that the pipe can smoothly separate from the arc frame 903 during the forward movement of the first rack 5, sliding seat 3 and water tank after the insertion is completed. After the pipe separates from the arc frame 903, the arc frame 903, pipe, baffle 905, round rod 907, top plate 909 and elastic telescopic rod 910 move upward synchronously and reset through the docking cylinder 902. The presence of the elastic telescopic rod 910 ensures that the top plate 909, baffle 905 and round rod 907 can be reset smoothly.

[0033] like Figure 2 , Figure 4 and Figure 6As shown, limiting mechanisms 10 are installed on both the left and right side walls of the processing table 1. The limiting mechanisms 10 are used to limit the water tank to ensure that the water tank remains stationary during the insertion of the pipe by the docking mechanism 9. The limiting mechanism 10 includes a support platform fixedly installed on the side wall of the processing table 1. An inverted L-shaped frame 1001 is fixedly installed on the support platform. A limiting rod 1002 that penetrates the L-shaped frame 1001 is movably installed on the horizontal section of the L-shaped frame 1001. The bottom end face of the limiting rod 1002 is hemispherical. An end plate 1003 is fixedly installed on the top of the limiting rod 1002. A limiting spring 1004 sleeved on the limiting rod 1002 is fixedly connected between the end plate 1003 and the L-shaped frame 1001. A vertically fixed device is installed on the limiting rod 1002. A limiting strip 1005 is installed through the L-shaped frame 1001. A connecting rod 1006 is fixedly installed on the end plate 1003. A guide rod 1007 is vertically fixedly installed at the end of the connecting rod 1006. A horizontal plate 12 is fixedly installed at the top of the vertical shaft 7. An annular guide plate 13 corresponding to the position of the guide rod 1007 is fixedly installed on the horizontal plate 12. A ball is installed at the bottom of the guide rod 1007 that fits against the top surface of the annular guide plate 13. The annular guide plate 13 is composed of a first arc segment and a second arc segment. The top surfaces of the first arc segment and the second arc segment are both horizontal, and the top surface of the second arc segment is higher. The connection point on one side of the first arc segment and the second arc segment is a vertical surface, and the connection point on the other side of the first arc segment and the second arc segment is an inclined surface.

[0034] As the vertical shaft 7 and the first missing gear 8 are continuously rotated by the drive motor 6, the horizontal plate 12 and the annular guide plate 13 rotate synchronously and continuously. Before the first missing gear 8 and the first rack 5 enter the meshing state, the higher second arc segment on the annular guide plate 13 pushes the guide rod 1007 upward. The connecting rod 1006, the end plate 1003, and the limiting rod 1002 rise under the limiting action of the limiting bar 1005. The limiting spring 1004 is stretched, and the limiting rod 1002 moves the water tank interface forward. The space is cleared; subsequently, the first missing gear 8 and the first rack 5 engage, the water tank interface moves forward a certain distance, and after the first missing gear 8 and the first rack 5 disengage, the guide rod 1007 also separates from the higher second arc segment on the annular guide plate 13. The rebound force of the limiting spring 1004 causes the connecting rod 1006, end plate 1003 and limiting rod 1002 to move downward and reset under the limiting action of the limiting strip 1005. The bottom end of the guide rod 1007 and the lower first arc segment on the annular guide plate 13... The segments fit together, and the limiting rod 1002 is simultaneously inserted into the water tank interface. The limiting rod 1002 limits the water tank and prevents it from moving back and forth during pipe installation. It should be noted that because the docking accuracy requirements between the pipe port and the water tank interface are high, the engagement of the first gear 8 and the first rack 5 cannot guarantee that the pipe port will be aligned with the water tank interface before each docking. Since the bottom end face of the limiting rod 1002 is hemispherical, and the friction between the guide rail 2 and the sliding seat 3 is small due to the presence of the ball 303, the limiting rod 1002 will interact with the water tank interface before being inserted into the water tank interface. During this process, the limiting rod 1002 pushes the water tank as a whole to move slightly, thereby improving the docking accuracy between the pipe port and the water tank interface. After the docking mechanism 9 has finished docking a single pipe, the higher second arc segment on the annular guide plate 13 pushes the guide rod 1007 upward again, and the limiting rod 1002 moves out of the water tank interface to ensure that the water tank can move forward smoothly.

[0035] The working process of the heating tube fixing and installation equipment used for energy storage heating in this embodiment is as follows: The operator first pulls the groove 301 at the rear end to drive the sliding seat 3 to move backward until the sliding seat 3 presses against the stop block 11 at the rear end. Then, the water tank is placed on the sliding seat 3, and the water tank is positioned and clamped by the clamping block 4. Then, the drive motor 6 is started so that the sliding seat 3 and the water tank move synchronously and equidistantly at intervals.

[0036] With the water tank stationary, a single pipe is manually placed into the arc groove 904 on the arc frame 903. Then, the docking mechanism 9 positions and adjusts the pipe before inserting it into the corresponding water tank interface. During this process, the limiting rod 1002 in the limiting mechanism 10 is inserted into the next water tank interface to be connected, thereby limiting the water tank to ensure that it remains stationary. After the docking mechanism 9 inserts the single pipe into the corresponding water tank interface, the limiting mechanism 10 releases the limiting of the water tank, and the sliding seat 3, the water tank, and the pipe connected to the water tank continue to move forward a certain distance. Then, the docking mechanism 9 resets.

[0037] Repeat the above process until the last pipe is inserted. Since there is no more water tank interface to be inserted and no longer needs to cooperate with the limiting mechanism 10, the sliding seat 3 is pressed against the front stop 11 by the groove 301 at the front end to limit the water tank. After the last pipe is inserted, the front stop 11 is pressed down by the operator, and the sliding seat 3 and the water tank continue to move forward until the last pipe is separated from the arc frame 903. In this state, the clamping block 4 is released from the water tank, and the installed pipe and water tank are removed by the operator. Finally, the drive motor 6 is turned off, and the sliding seat 3 is moved backward along the guide rail 2 by pulling the groove 301 at the rear end to reset. The front stop 11 will automatically reset under the action of the elastic force.

[0038] The above description is merely a preferred embodiment of the present invention and is not intended to limit the invention. Various modifications and variations can be made to the present invention by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the scope of protection of the present invention.
