Description

Technical Field

[0001] This utility model belongs to the field of pumping technology, specifically relating to a press-fitting device. Background Technology

[0002] The pumping unit is the core component of concrete pumping machinery, responsible for transporting concrete from the hopper to the pipeline and ensuring its stable and efficient flow. The structural design of this unit is crucial; it mainly consists of the hopper, concrete cylinder, pumping reversing mechanism, and control system.

[0003] The pump reversing mechanism plays a crucial role in the pumping process, controlling the reversing motion of the concrete cylinders. The pump reversing mechanism typically includes a spectacle plate and a transition sleeve. The spectacle plate enables effective switching between concrete cylinders, while the transition sleeve passes through mounting holes in the hopper, with its ends abutting against the spectacle plate and the concrete cylinder respectively. Concrete in the cylinders can pass through the transition sleeve and continue flowing.

[0004] To ensure the transition sleeve is securely fixed in the mounting hole of the hopper, the traditional method is to manually press it in. However, this manual pressing method is not only time-consuming but also inefficient, easily leading to production delays and affecting overall production efficiency. Utility Model Content

[0005] In view of the above-mentioned defects or deficiencies, this utility model provides a pressing device, which aims to solve the technical problem of low efficiency in manual pressing of transition sleeves.

[0006] To achieve the above objectives, this utility model provides a pressing device for pressing a transition sleeve into the mounting hole of a hopper. The transition sleeve is a hollow sleeve. The pressing device includes a mounting bracket, a pressing drive component, and a clamping assembly. The pressing drive component is mounted on the mounting bracket. The clamping assembly includes a pressing base, an abutment end plate assembly, and a diameter-changing positioning mechanism. The pressing base is driven to the telescopic end of the pressing drive component. The abutment end plate assembly is mounted on the pressing base and can abut the transition sleeve axially. The diameter-changing positioning mechanism is mounted on the pressing base or the abutment end plate assembly and can extend into the inner side of the transition sleeve to abut radially.

[0007] In this embodiment of the utility model, the variable diameter positioning mechanism includes a variable diameter drive and a variable diameter claw. The variable diameter drive is disposed on the press-fit base or the abutment end plate assembly. The number of variable diameter claws is at least two. The at least two variable diameter claws are respectively driven and connected to the variable diameter drive. The variable diameter drive can drive the at least two variable diameter claws to move in a direction closer to or away from the transition sleeve inside the transition sleeve.

[0008] In this embodiment of the utility model, the variable diameter claw includes a clamping rod that is driven and connected to the variable diameter drive member, and a clamping plate that is connected to the outer side of the clamping rod. The outer edges of at least two clamping rods are inclined to each other in the direction of extending into the transition sleeve. The clamping plate can radially abut against the straight transition sleeve. The clamping rod located on the side of the clamping plate away from the variable diameter drive member can radially abut against the tapered transition sleeve.

[0009] In this embodiment of the invention, the outer side of the clamping plate is arc-shaped.

[0010] In this embodiment of the invention, the diameter of the clamping rod gradually decreases in the direction of extending into the transition sleeve.

[0011] In this embodiment of the utility model, the abutting end plate assembly includes a straight sleeve end plate and a conical sleeve end plate that are spaced apart and connected. The straight sleeve end plate is used to abut against the straight transition sleeve end, and the conical sleeve end plate is used to abut against the conical transition sleeve end. The variable diameter claw can extend out of the conical sleeve end plate.

[0012] In this embodiment of the utility model, a guide sleeve is provided on the mounting bracket, and a guide rod is provided on the press-fit base, with the guide rod sleeved inside the guide sleeve.

[0013] In this embodiment of the utility model, the press-fitting drive component includes a telescopic drive component and a telescopic rod. The telescopic drive component and the press-fitting base are respectively disposed on opposite sides of the mounting bracket. The telescopic drive component is driven to connect with the telescopic rod. The telescopic end of the telescopic rod is disposed on the side of the mounting bracket close to the press-fitting base and is connected to the press-fitting base.

[0014] In this embodiment of the utility model, the mounting bracket includes a main body, a translation mechanism, a lifting mechanism, and a lifting plate. The translation mechanism can drive the lifting mechanism to translate relative to the main body, and the lifting mechanism can drive the lifting plate to rise and fall. The pressing drive component is disposed on the lifting plate.

[0015] In this embodiment of the utility model, the main body includes a pressing part and a supporting part connected to each other. A first mounting surface is formed on the pressing part for mounting a translation mechanism, and a second mounting surface is formed on the supporting part that is lower than the first mounting surface. The second mounting surface is for mounting a conveying mechanism, and the conveying direction of the conveying mechanism is made to be consistent with the translation direction of the lifting mechanism.

[0016] In this embodiment of the utility model, a lifting mechanism is provided on the support part. The lifting mechanism is used to drive the hopper to rise and fall so that the hopper is separated from the conveying mechanism.

[0017] Through the above technical solution, the press-fitting device provided by this utility model embodiment has the following beneficial effects:

[0018] In this invention, a press-fitting drive component is mounted on a mounting bracket and is drivenly connected to a press-fitting base. The press-fitting drive component can drive the press-fitting base to extend and retract, thereby pressing the transition sleeve into the mounting hole of the hopper. An abutment plate assembly is disposed on the press-fitting base, and the movement of the press-fitting base drives the abutment plate assembly to move. The movement of the abutment plate assembly allows it to abut against the end of the transition sleeve; that is, the end of the transition sleeve can abut against the abutment plate assembly, so that the movement of the abutment plate assembly can drive the transition sleeve to move, thereby pressing the transition sleeve into the mounting hole.

[0019] The variable diameter positioning mechanism is mounted on the press-fit base, or on the abutment end plate assembly, to enable its installation and fixation. The variable diameter positioning mechanism can extend into the inner side of the transition sleeve and can move with a variable diameter to abut against the inner wall of the transition sleeve radially, thereby clamping the transition sleeve and pressing it into the mounting hole.

[0020] By setting the end plate assembly to abut against the transition sleeve end-to-end, and setting the variable diameter positioning mechanism to abut against the transition sleeve radially to clamp the transition sleeve, the pressing device can automatically press the transition sleeve, thereby improving the pressing efficiency.

[0047] The specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are for illustration and explanation only and are not intended to limit the scope of this utility model.

[0048] The pressing device of this utility model is described below with reference to the accompanying drawings.

[0049] like Figures 1 to 6 As shown, this utility model provides a pressing device 10, which is used to press a transition sleeve 204 into the mounting hole 2011 of the hopper 201. The transition sleeve 204 is in the shape of a hollow sleeve. The pressing device 10 includes a mounting bracket 17, a pressing drive component 11, and a clamping assembly. The pressing drive component 11 is mounted on the mounting bracket 17. The clamping assembly includes a pressing base 12, an abutting end plate assembly 13, and a variable diameter positioning mechanism 14. The pressing base 12 is driven to the telescopic end of the pressing drive component 11. The abutting end plate assembly 13 is mounted on the pressing base 12 and can abut the transition sleeve 204 axially. The variable diameter positioning mechanism 14 is mounted on the pressing base 12 or the abutting end plate assembly 13 and can extend into the inside of the transition sleeve 204 to abut the transition sleeve 204 radially.

[0050] Please see Figure 1 and Figure 2 The pumping reversing mechanism includes a spectacle plate and a transition sleeve 204. The spectacle plate enables effective switching between concrete cylinders, while the transition sleeve 204 passes through a mounting hole 2011 on the hopper 201, with its two ends abutting against the spectacle plate and the concrete cylinder respectively. Concrete in the concrete cylinder can pass through the transition sleeve 204 and continue to flow. Figure 2 As shown, each hopper 201 has two transition sleeves 204. The transition sleeves 204 are installed in the mounting holes 2011 of the hopper 201, and the inner end face of the transition sleeves 204 is flush with the spectacle plate.

[0051] Please see Figure 3 The press-fit drive component 11 is mounted on the mounting bracket 17 and is drivenly connected to the press-fit base 12. The press-fit drive component 11 can drive the press-fit base 12 to extend and retract, thereby pressing the transition sleeve 204 into the mounting hole 2011 of the hopper 201. The abutment end plate assembly 13 is disposed on the press-fit base 12. The movement of the press-fit base 12 drives the abutment end plate assembly 13 to move. The movement of the abutment end plate assembly 13 allows the abutment end plate assembly 13 to abut against the end of the transition sleeve 204. That is, the end of the transition sleeve 204 can abut against the abutment end plate assembly 13, so that the movement of the abutment end plate assembly 13 can drive the movement of the transition sleeve 204, thereby pressing the transition sleeve 204 into the mounting hole 2011.

[0052] The variable diameter positioning mechanism 14 is disposed on the press-fit base 12, or on the abutment end plate assembly 13, to realize the installation and fixation of the variable diameter positioning mechanism 14. The variable diameter positioning mechanism 14 can extend into the inner side of the transition sleeve 204, and the variable diameter positioning mechanism 14 can move with a variable diameter to abut against the inner wall of the transition sleeve 204 from the radial direction, so that the variable diameter positioning mechanism 14 can clamp the transition sleeve 204 and press the transition sleeve 204 into the mounting hole 2011.

[0053] By setting the end plate assembly 13 to abut against the transition sleeve 204 at the end, and setting the variable diameter positioning mechanism 14 to abut against the transition sleeve 204 in the radial direction to clamp the transition sleeve 204, the pressing device 10 can automatically press the transition sleeve 204, thereby improving the pressing efficiency.

[0054] In this embodiment of the utility model, please refer to Figure 3 The variable diameter positioning mechanism 14 includes a variable diameter drive 144 and a variable diameter claw 141. The variable diameter drive 144 is disposed on the press-fit base 12 or the abutment end plate assembly 13. The number of variable diameter claws 141 is at least two. At least two variable diameter claws 141 are respectively driven connected to the variable diameter drive 144. The variable diameter drive 144 can drive at least two variable diameter claws 141 to move in a direction closer to or away from the transition sleeve 204 inside the transition sleeve 204.

[0055] The variable diameter drive component 144 is disposed on the press-fit base 12 or the abutment end plate assembly 13 to realize the installation and fixation of the variable diameter drive component 144. The number of variable diameter claws 141 is at least two, so that the variable diameter claws 141 can clamp the transition sleeve 204 more stably and reliably. Figure 3 The number of diameter-changing claws 141 is three. For ease of description, the following example uses three diameter-changing claws 141. In other embodiments, the number of diameter-changing claws 141 can be four, five or other numbers. The number of diameter-changing claws 141 can be flexibly adjusted according to actual needs.

[0056] The variable diameter claws 141 extend towards the side of the abutting end plate assembly 13 away from the press-fit base 12. The three variable diameter claws 141 are respectively driven and connected to the variable diameter drive member 144. The variable diameter claws 141 first extend into the transition sleeve. The variable diameter drive member 144 drives the three variable diameter claws 141 to move in a variable diameter direction, causing the three variable diameter claws 141 to move away from each other, so that the three variable diameter claws 141 respectively abut against the inner wall of the transition sleeve 204 from the radial direction, thereby clamping the transition sleeve. The press-fit drive member 11 drives the abutting end plate assembly 13 to move, pressing the transition sleeve 204 into the mounting hole 2011. After the transition sleeve 204 is pressed into the mounting hole 2011, the variable diameter drive member 144 drives the three variable diameter claws 141 to move in a variable diameter direction, causing the three variable diameter claws 141 to move closer to each other, so that the three variable diameter claws 141 respectively disengage from the inner wall of the transition sleeve 204, thereby releasing the transition sleeve 204.

[0057] Specifically, the variable diameter drive component 144 drives the three variable diameter claws 141 to move in a variable diameter manner, which can be referred to the structural design of a three-jaw chuck.

[0058] In another embodiment, the variable diameter positioning mechanism 14 can be an elastic element. The elastic element is compressed and then inserted into the transition sleeve 204. The elastic element elastically recovers within the transition sleeve 204 to abut against the inner wall of the transition sleeve 204, thereby enabling the variable diameter positioning mechanism 14 to extend into the inner side of the transition sleeve 204 and radially abut against the transition sleeve 204.

[0059] In the embodiments of this application, please refer to Figure 3 The variable diameter claw 141 includes a clamping rod 1411 drivenly connected to the variable diameter drive member 144, and a clamping plate 1412 connected to the outside of the clamping rod 1411. At least two clamping rods 1411 are inclined close to each other in the direction of extending into the transition sleeve 204. The clamping plate 1412 can radially abut against the straight transition sleeve. The clamping rod 1411 located on the side of the clamping plate 1412 away from the variable diameter drive member 144 can radially abut against the tapered transition sleeve.

[0060] The transition sleeve 204 is divided into a straight transition sleeve and a tapered transition sleeve. The straight transition sleeve has a consistent inner diameter, while the tapered transition sleeve has a tapered inner diameter profile. The inner diameter of the tapered transition sleeve is set to narrow inward from the end plate assembly 13 toward the direction away from the press-fit base 12.

[0061] A clamping plate 1412 is connected to the outside of the clamping rod 1411. The clamping plate 1412 extends radially and is used to abut against the inner wall of the straight transition sleeve to clamp the straight transition sleeve.

[0062] The outer edges of the three clamping rods 1411 are inclined close to each other in the direction of extending into the transition sleeve 204. That is, in the direction of extending into the transition sleeve 204, the diameter of the circle formed by the outer edges of the three clamping rods 1411 gradually decreases, so that the three clamping rods 1411 can form a variable diameter to match the inner diameter profile of the tapered transition sleeve and abut against the inner wall of the tapered transition sleeve to clamp the tapered transition sleeve.

[0063] By setting the clamping plate 1412 and the clamping rod 1411, the variable diameter claw 141 can be compatible with straight transition sleeves and tapered transition sleeves, so that the use of the clamping assembly can be more flexible and convenient, and can adapt to more application scenarios.

[0064] In this embodiment, the diameter of the clamping rod 1411 gradually decreases in the direction toward insertion into the transition sleeve 204. That is, the clamping rod 1411 is a tapered rod with a gradually decreasing diameter in the direction toward insertion into the transition sleeve 204, such that the outer edges of the three clamping rods 1411 are inclined close to each other. Furthermore, the gradually decreasing diameter of the clamping rod 1411 facilitates insertion into the tapered transition sleeve.

[0065] In another embodiment, the clamping rods 1411 may be round rods with a consistent diameter, and the clamping rods 1411 are inclined as a whole, such that the outer edges of the three clamping rods 1411 are inclined close to each other in the direction of extending into the transition sleeve 204.

[0066] In this embodiment, the outer side of the clamping plate 1412 is arc-shaped, which increases the contact area between the clamping plate 1412 and the straight transition sleeve, so that the clamping plate 1412 can more stably and reliably abut against the inner wall of the straight transition sleeve.

[0067] In the embodiments of this application, please refer to Figure 3 The abutting end plate assembly 13 includes a straight sleeve end plate 131 and a tapered sleeve end plate 132 that are spaced apart and connected. The straight sleeve end plate 131 is used to abut against the straight transition sleeve end, and the tapered sleeve end plate 132 is used to abut against the tapered transition sleeve end. The variable diameter claw 141 can extend out of the tapered sleeve end plate 132.

[0068] The straight end plate 131 and the conical end plate 132 are connected by a connector 133, and the straight end plate 131 and the conical end plate 132 are spaced apart by the connector 133.

[0069] When the transition sleeve 204 is a straight transition sleeve, the inner wall of the straight transition sleeve abuts against the clamping plate 1412, and the clamping plate 1412 supports the straight transition sleeve. The end of the straight transition sleeve abuts against the straight sleeve end plate 131, and the press-fitting drive member 11 drives the straight sleeve end plate 131 to move, and the straight sleeve end plate 131 pushes the straight transition sleeve to move, so as to press the straight transition sleeve into the mounting hole 2011.

[0070] When the transition sleeve 204 is a tapered transition sleeve, the inner wall of the tapered transition sleeve abuts against the clamping rod 1411 located on the side of the clamping plate 1412 away from the variable diameter drive member 144, and the clamping rod 1411 supports the tapered transition sleeve. The end of the tapered transition sleeve abuts against the tapered sleeve end plate 132, and the pressing drive member 11 drives the tapered sleeve end plate 132 to move, and the tapered sleeve end plate 132 pushes the tapered transition sleeve to move, so as to press the tapered transition sleeve into the mounting hole 2011.

[0071] By setting a straight end plate 131 and a tapered end plate 132, the abutting end plate assembly 13 can be compatible with both straight transition sleeves and tapered transition sleeves, making the use of the abutting end plate assembly 13 more flexible and convenient.

[0072] Understandably, the radial dimension of the tapered end plate 132 is smaller than that of the straight end plate 131. Furthermore, both the straight end plate 131 and the tapered end plate 132 have clearance grooves 134, through which the clamping rod 1411 passes sequentially. The clamping plate 1412 is located within the clearance groove 134 of the tapered end plate 132. The clearance groove 134 extends radially and guides the radial movement of the variable diameter claw 141, making its radial movement more stable and reliable.

[0073] In this embodiment of the utility model, please refer to Figure 4 and Figure 5 The mounting bracket 17 is provided with a guide sleeve 171, and the press base 12 is provided with a guide rod 121, which is sleeved inside the guide sleeve 171.

[0074] A guide sleeve 171 is mounted on the mounting bracket 17, and a guide rod 121 is mounted on the press-fit base 12. The extension direction of the guide sleeve 171 and the guide rod 121 is consistent with the telescopic direction. The guide rod 121 is sleeved inside the guide sleeve 171 and can move relative to the guide sleeve 171. During the process of the press-fit drive component 11 driving the press-fit base 12 to move relative to the mounting bracket 17, the guide rod 121 moves relative to the guide sleeve 171. Through the cooperation of the guide rod 121 and the guide sleeve 171, the telescopic movement of the press-fit base 12 is guided, making the press-fitting process of the press-fit base 12 pressing the transition sleeve 204 more stable and reliable.

[0075] like Figure 5 As shown, there can be two guide rods 121 and two guide sleeves 171. The press-fitting drive component 11 is located between the two guide rods 121 to further improve the guiding effect and make the force on the press-fitting base 12 more uniform.

[0076] In this embodiment of the utility model, please refer to Figure 4 and Figure 5 The press-fitting drive component 11 includes a telescopic drive component and a telescopic rod. The telescopic drive component and the press-fitting base 12 are respectively located on opposite sides of the mounting bracket 17. The telescopic drive component is driven to connect with the telescopic rod. The telescopic end of the telescopic rod is located on the side of the mounting bracket 17 near the press-fitting base 12 and is connected to the press-fitting base 12.

[0077] The telescopic drive component can be a pneumatic cylinder or a hydraulic cylinder, and the telescopic rod is the piston rod of the pneumatic or hydraulic cylinder, possessing high stability and reliability. The telescopic drive component can also be a motor lead screw or other drive structures; this application does not limit the specific driving method of the telescopic drive component.

[0078] The telescopic drive and the pressing base 12 are respectively located on opposite sides of the mounting bracket 17, making the structure of the pressing device 10 more compact. The telescopic drive is driven to extend and retract the telescopic rod, and the telescopic end of the telescopic rod is connected to the pressing base 12. The telescopic drive drives the telescopic rod to extend and retract, and the telescopic rod drives the pressing base 12 to move, so that the pressing base 12 can press the transition sleeve 204 into the mounting hole 2011 of the hopper 201.

[0079] In this embodiment of the utility model, please refer to Figure 4 and Figure 6 The mounting bracket 17 includes a main body 172, a translation mechanism 15, a lifting mechanism 16, and a lifting plate 173. The translation mechanism 15 can drive the lifting mechanism 16 to translate relative to the main body 172, and the lifting mechanism 16 can drive the lifting plate 173 to rise and fall. The press-fitting drive component 11 is provided on the lifting plate 173.

[0080] The translation mechanism 15 can drive the lifting mechanism 16 to translate horizontally relative to the main body 172, adjusting its horizontal position in a timely manner. This allows the pressing device 10 to press the two transition sleeves 204 into the corresponding mounting holes 2011, making the pressing device 10 more flexible and convenient to use. The lifting mechanism 16 can drive the lifting plate 173 to rise and fall. The pressing drive component 11 is mounted on the lifting plate 173. The rise and fall of the lifting plate 173 drives the pressing drive component 11 to rise and fall, which in turn drives the pressing base 12 to rise and fall. This allows the vertical position of the pressing base 12 to be flexibly adjusted according to the position of the mounting holes 2011, improving the flexibility of the pressing device 10.

[0081] Specifically, the translation mechanism 15 includes a translation base 151 and a translation drive assembly 152. The translation drive assembly 152 is connected to the main body 172 and is drivenly connected to the translation base 151. The translation drive assembly 152 may include a translation motor 1521 and a translation screw 1522. The translation motor 1521 is connected to the main body 172 and is drivenly connected to the translation screw 1522. The translation screw 1522 is threadedly connected to the translation base 151. The translation motor 1521 drives the translation screw 1522 to rotate, and the translation screw 1522 drives the translation base 151 to move relative to the main body 172. The translation base 151 and the main body 172 are slidably connected via a slider and slide rail, which guides the translation base 151 to move stably and reliably.

[0082] The lifting mechanism 16 includes a lifting base 161 and a lifting drive assembly 162. The lifting base 161 is connected to the translation base 151, and the lifting drive assembly 162 is connected to both the lifting base 161 and the lifting plate 173. The lifting drive assembly 162 may include a lifting motor 1621 and a lifting screw 1622. The lifting motor 1621 is connected to the lifting base 161 and is driven by the lifting screw 1622. The lifting screw 1622 is threadedly connected to the lifting plate 173. The lifting motor 1621 drives the lifting screw 1622 to rotate, which in turn causes the lifting plate 173 to rise and fall relative to the lifting base 161. The lifting plate 173 then drives the pressing drive component 11 to rise and fall, thereby enabling the pressing base 12 to rise and fall. The lifting plate 173 and the lifting base 161 are slidably connected via a slider rail, which provides guidance and improves the stability and reliability of the lifting plate 173 during its lifting process.

[0083] The translation drive assembly 152 and the lifting drive assembly 162 can also be cylinders or other structures capable of being driven.

[0084] It is understandable that there can be two clamping assemblies, with each clamping assembly corresponding to one of the two mounting holes 2011 of the hopper 201, to achieve synchronous pressing of the two transition sleeves 204 and improve work efficiency.

[0085] In this embodiment of the utility model, please refer to Figure 6 The main body 172 includes a pressing part 1721 and a support part 1722 connected to each other. The pressing part 1721 has a first mounting surface for mounting the translation mechanism 15. The support part 1722 has a second mounting surface that is lower than the first mounting surface. The second mounting surface can be used for mounting the conveying mechanism, and the conveying direction of the conveying mechanism can be set to be consistent with the translation direction of the lifting mechanism 16.

[0086] The translation mechanism 15 is mounted on the first mounting surface of the pressing part 1721, and a second mounting surface is formed on the support part 1722. The second mounting surface is set lower than the first mounting surface, so that a conveying gap 1723 is formed between the pressing part 1721 and the support part 1722. The second mounting surface can be used for the installation of the conveying mechanism, which passes through the conveying gap 1723. By setting the second mounting surface lower than the first mounting surface to form the conveying gap 1723, the space is rationally arranged and utilized, making the structure of the pressing device 10 more compact. The conveying direction of the conveying mechanism is consistent with the translation direction of the lifting mechanism 16, which facilitates the pressing device 10 to press the transition sleeve 204 into the mounting hole 2011 of the hopper 201.

[0087] Specifically, the conveyor mechanism can be referenced from the belt conveyor structure.

[0088] A lifting mechanism (not shown) is provided on the support part 1722. The lifting mechanism is used to drive the hopper 201 to rise and fall so that the hopper 201 is separated from the conveying mechanism.

[0089] A lifting mechanism is mounted on the support 1722 and is used to drive the hopper 201 to rise and fall. The lifting mechanism drives the hopper 201 to rise, causing it to disengage from the conveying mechanism for easy pressing of the transition sleeve 204. The lifting mechanism also drives the hopper 201 to fall, returning it to the conveying mechanism so that the conveying mechanism can transfer the hopper 201 to the next workstation.
