Description

Technical Field

[0001] This application relates to the field of engineering machinery technology, specifically to a winch and a double-wheel groove milling machine. Background Technology

[0002] Twin-wheel trenching machines are a type of continuous wall excavation equipment. Especially when excavating walls, they generate a large amount of mud. The mud pipe winch is an important component on twin-wheel trenching machines for the release and retraction of mud pipes. Existing mud pipe winches have many parts and are relatively complex to assemble. A support plate needs to be installed on the inlet side of the mud pipe winch to allow mud to flow from one side of the drum to the other. A sealing plate is installed on the outlet side of the mud pipe winch to seal the grease chamber. Summary of the Invention

[0003] In view of this, this application provides a winch that eliminates the need for components such as a support disc, thereby simplifying the assembly process.

[0004] To achieve the above objectives, this application provides the following technical solution:

[0005] A winch, comprising:

[0006] cylindrical body;

[0007] An isolation assembly is disposed in the receiving cavity of the cylinder and isolates the receiving cavity into at least two sub-cavities;

[0008] The catheter has a first portion located within the receiving lumen, and at least one end of the first portion passes through the circumferential sidewall of the cylinder;

[0009] The first portion passes through the isolation component and is connected to the isolation component so that the first portion is fixedly supported by the isolation component.

[0010] Optionally, in the winch described above, the first part includes a connecting pipe section for connecting to the isolation assembly, the connecting pipe section being a rigid pipe.

[0011] Optionally, in the above-mentioned winch, an annular connector is sleeved on the connecting pipe section, the isolation assembly includes an annular fixing member, a connecting hole is provided on the bottom wall of the annular connector, and an installation hole is provided on the annular fixing member, the connecting hole and the installation hole are aligned and connected.

[0012] Optionally, in the winch described above, a sealing ring is provided on the circumferential sidewall of the annular connector to form a sealed connection with the isolation component. The annular connector is provided with a cover to cover the sealing ring, thereby preventing the sealing ring from coming out between the circumferential sidewall of the annular connector and the inner wall of the isolation component.

[0013] Optionally, in the above-mentioned winch, the annular connector has a connecting cavity, and a first reinforcing plate is provided in the connecting cavity. The first reinforcing plate connects the bottom wall and the circumferential side wall of the annular connector.

[0014] Optionally, in the above-mentioned winch, at least two first reinforcing plates are provided, and they are evenly distributed around the connecting pipe section.

[0015] Optionally, in the above-mentioned winch, a second reinforcing plate is provided on the connecting pipe section, and the second reinforcing plate is connected between the circumferential side wall of the connecting pipe section and the bottom wall of the annular connector.

[0016] Optionally, in the above-mentioned winch, at least two second reinforcing plates are provided, and they are evenly distributed around the connecting pipe section.

[0017] Optionally, in the above-mentioned winch, the isolation component is coaxially arranged with the cylinder, and the connecting pipe section is connected to the isolation component, with the connection position located at the axial center of the cylinder.

[0018] A twin-wheel grooving machine includes the winch described in any of the above claims.

[0019] This application provides a winch including a cylinder, an isolation assembly, and a conduit. The isolation assembly is disposed within the receiving cavity of the cylinder, dividing the receiving cavity into at least two sub-cavities. A portion of the conduit is located within the receiving cavity; this portion is referred to as a first section. The first section passes through and is connected to the isolation assembly, thereby achieving fixed support of the first section by the isolation assembly. Simultaneously, at least one end of the first section passes through the circumferential sidewall of the cylinder. The isolation assembly divides the receiving cavity into at least two sub-cavities, at least one of which is a lubrication cavity. The isolation assembly isolates the lubrication cavity separately, preventing dust ingress and lubricant leakage. Since at least one end of the first section passes through the cylinder and is directly connected to the cylinder, the use of other components such as support plates is eliminated, simplifying the assembly process. Furthermore, the elimination of other components such as support plates saves space, allowing for a relatively larger space at the connection point between the first section and the cylinder. This increases the bending radius of the pipe section connected to the cylinder, reducing the phenomenon of mud clogging. Attached Figure Description

[0026] This application provides a winch that eliminates the need for components such as a support plate, thereby simplifying the assembly process.

[0027] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0028] like Figure 1As shown in the illustration, this application provides a winch including a cylinder 2, an isolation component 5, and a conduit. The isolation component 5 is disposed within the receiving cavity of the cylinder 2, dividing the receiving cavity into at least two sub-cavities. A portion of the conduit is located within the receiving cavity; this portion is referred to as the first part. The first part passes through and is connected to the isolation component 5, thereby providing fixed support for the first part. Simultaneously, at least one end of the first part passes through the circumferential sidewall of the cylinder 2. Preferably, the isolation component 5 divides the receiving cavity into two sub-cavities, one of which is a lubrication cavity (i.e., a grease cavity). The isolation component 5 isolates the lubrication cavity separately, preventing dust ingress and lubricant leakage. In other words, this isolation component 5 can function as a sealing disc in the prior art. At least one end of the first section passes through the cylinder 2 and is directly connected to the cylinder 2, saving the use of other components such as support plates, simplifying the assembly process. Simultaneously, by saving the use of other components, the space occupied by these components is also saved, allowing for a relatively larger space at the connection point between the first section and the cylinder 2. This increases the bending radius of the pipe section connected to the cylinder 2, reducing the phenomenon of mud clogging the pipe. It should be noted that the support plate is made of steel; saving the use of support plates and other components saves on steel consumption and reduces costs. The first section passes through and is connected to the isolation component 5. In this way, the isolation component 5 provides support for the first section, saving the use of other support components and simplifying assembly.

[0029] Furthermore, such as Figure 2 and Figure 3As shown, the first part includes a connecting pipe section 35 for connecting to the isolation component 5. The connecting pipe section 35 is a rigid pipe. Both ends of the connecting pipe section 35 are connected to conductive pipe sections. At least one of the two ports of the connecting pipe section 35 is provided with a radial flange 34 for connecting the conductive pipe section at least one end. That is, the first part includes a pipe section connected to the isolation component 5, referred to as the connecting pipe section 35. The connecting pipe section 35 is a rigid pipe. Both ends of the connecting pipe section 35 are connected to conductive pipe sections. One or both ports of the two ports (i.e., the inlet end and the outlet end) of the connecting pipe section 35 are provided with a radial flange 34 to facilitate connecting the conductive pipe section on the connecting pipe section 35. The winch in this application is a component used to transport mud during foundation excavation in engineering. The outer peripheral wall of the winch is wound with a slurry pipe for transporting mud. When excavating the foundation, the winch rotates, releasing the wound slurry pipe and lowering it. The slurry pipe draws up the excavated mud and transmits it to a conduit (this conduit is the slurry pipe used to guide the mud) set inside the winch. Since the mud being transported has a certain weight, and the cylinder 2 of the winch has a certain width, that is to say, mud with a certain weight needs to be transported from one end of the conduit inside the winch to the other end. This requires a component to support the conduit inside the winch to complete the mud transport. It should be noted that the supporting component is the isolation component 5, which is made of rigid material. In order to better match the isolation component 5 and without affecting the isolation function of the isolation component 5, the connecting pipe section 35 on the conduit that connects to the isolation component 5 is also made of rigid material. One or both ports of the connecting pipe section 35 are provided with a radial flange 34. The radial flange 34 protrudes radially from the pipe wall. The protruding part can be connected to the conductive pipe section by common connection methods, such as by flange connection, which makes the connection simple and the operation convenient. The connecting pipe section 35 is a pipe section connected to and supported by the isolation component 5. The isolation component 5 completely divides the inner cavity of the cylinder 2 into at least two chambers, at least one of which is a lubrication chamber. The slewing bearing 1 in the lubrication chamber, driven by a motor, lowers the slurry pipe wound on the winch to the slurry location as the winch cylinder 2 rotates, preparing for slurry transport. One end of the connecting pipe section is connected to the slurry pipe, and the other end is connected to the connecting pipe section 35, so that after the slurry enters the connecting pipe section from the slurry pipe, it is transported along the transport channel of the connecting pipe section 35 and the connecting pipe section. The connecting pipe section 35, the isolation component 5, and the connecting pipe section cooperate to achieve smooth slurry transport. Alternatively, the two ends of the connecting pipe section 35 may not have radial flanges 34; instead, clamps can be used to connect the connecting pipe section 35 to the connecting pipe section. Alternatively, flanged short pipes 38 can be directly connected to the two ends of the connecting pipe section 35, connecting the flanged short pipes 38 to the connecting pipe section.

[0030] Furthermore, such as Figure 2As shown, an annular connector 3 is fitted onto the connecting pipe section 35. The isolation assembly 5 includes an annular fixing member. A connecting hole is provided on the bottom wall 32 of the annular connector 3, and a mounting hole is provided on the annular fixing member. The connecting hole and the mounting hole are aligned and connected. That is, the annular connector 3 is fitted onto the connecting pipe section 35, and the connecting hole on the bottom wall 32 of the annular connector 3 is aligned and connected to the mounting hole of the annular fixing member on the isolation assembly 5. The alignment and connection of the connecting hole and the mounting hole achieves the connection between the annular connector 3 and the isolation assembly 5. The annular connector 3 provides support for the connecting pipe segment 35. Preferably, the annular connector 3 and the connecting pipe segment 35 are fixedly connected, making the support provided by the annular connector 3 for the connecting pipe segment 35 more stable. Simultaneously, the connecting hole and the mounting hole are aligned and fixedly connected by bolts. This achieves the connection between the annular connector 3 and the annular fastener. The annular fastener is fixedly mounted on the isolation component 5, meaning that the annular connector 3 and the isolation component 5 are fixedly connected. In other words, the annular connector 3 achieves a fixed connection with the isolation component 5 through the connecting hole in the bottom wall, simplifying assembly. Furthermore, the connecting pipe segment 35 and the annular connector 3 can be integrally formed, for example, integrally formed in a casting mold.

[0031] Furthermore, such as Figure 1 and Figure 3 As shown, a sealing ring 4 is provided on the circumferential sidewall 33 of the annular connector 3 to form a sealed connection with the isolation component 5. A cover 36 is provided on the annular connector 3 to cover the sealing ring 4, preventing the sealing ring 4 from coming off between the circumferential sidewall 33 of the annular connector 3 and the inner wall of the isolation component 5. That is, a sealing ring 4 is provided on the circumferential sidewall 33 of the annular connector 3. As can be seen from the above, the annular connector 3 and the isolation component 5 are fixedly connected. In this way, the connection between the annular connector 3 and the isolation component 5 is not only a fixed connection but also a sealed connection. In order to prevent the sealing ring 4 from coming off between the circumferential sidewall 33 of the annular connector 3 and the inner wall of the isolation component 5, a cover 36 is provided on the annular connector 3 to cover the sealing ring 4. A sealing ring 4 is provided between the circumferential sidewall 33 of the annular connector 3 and the inner wall of the isolation component 5, ensuring a sealed connection between the annular connector 3 and the isolation component 5. Since the isolation component 5 is used to separate the inner cavity of the cylinder 2, and at least one of these cavities is a grease cavity, it is necessary to provide a sealing ring 4 between the annular connector 3 and the isolation component 5 to achieve a sealed connection. This connection method facilitates the sealing of the grease cavity, preventing leakage and the entry of external dust. The annular connector 3 is provided with a cover 36 to cover the sealing ring 4, meaning that the sealing ring 4 can be securely placed, ensuring a safe and reliable sealed connection between the isolation component 5 and the annular connector 3. Alternatively, the sealing ring 4 may not be provided on the circumferential sidewall 33 of the annular connector 3.

[0032] In optional embodiments, such as Figure 3 As shown, a first reinforcing plate 37 is provided in the connecting cavity. The first reinforcing plate 37 connects the bottom wall 32 and the circumferential side wall 33 of the annular connector 3. That is, the annular connector 3 has an inner cavity, in which the first reinforcing plate 37 is provided. The first reinforcing plate 37 is located between the bottom wall 32 and the circumferential side wall 33 of the annular connector 3. The annular connector 3 is an annular piece sleeved on the connecting pipe section 35, providing support for the connecting pipe section 35. When the annular connector 3 has a connecting cavity, the annular connector 3 is a connecting ring. The first reinforcing plate 37 is provided between the bottom wall and the circumferential side wall of the connecting ring to strengthen the connection between the bottom wall and the circumferential side wall, making the connecting ring itself structurally stable. At this time, the supporting effect of the connecting ring on the connecting pipe section 35 is also more solid. In this way, the mud transportation process is smoother. Alternatively, the first reinforcing plate 37 may not be provided in the connecting cavity.

[0033] Furthermore, at least two first reinforcing plates 37 are provided, and they are evenly distributed around the circumference of the connecting pipe segment 35. That is, at least two first reinforcing plates 37 are provided, and more may also be provided. The first reinforcing plates 37 are evenly distributed between the bottom wall 32 and the circumferential side wall 33 of the annular connector 3 with the connecting pipe segment 35 as the center, in order to improve the reinforcement effect and the stress balance of the connecting pipe segment 35. When two first reinforcing plates 37 are provided, one first reinforcing plate 37 is located between the bottom wall 32 and the circumferential side wall 33 of the annular connector 3, and the other is located between the bottom wall 32 and the circumferential side wall 33 of the annular connector 3 at a 180-degree angle to the aforementioned first reinforcing plate 37. When three first reinforcing plates 37 are provided, the angle between any two reinforcing plates is 120 degrees. When multiple first reinforcing plates are provided, the same principle applies. Because the winch needs to rotate when lowering the slurry pipe, when the first reinforcing plates 37 are evenly distributed around the circumference of the connecting pipe, the annular connecting member 3 experiences uniform force during the rotation of the winch. Furthermore, when two first reinforcing plates 37 are provided, they can be positioned at locations where the force on the connecting pipe section 35 is concentrated during slurry transportation.

[0034] In optional embodiments, such as Figure 3 As shown, a second reinforcing plate 31 is provided on the connecting pipe section 35. The second reinforcing plate 31 connects the circumferential sidewall of the connecting pipe section 35 and the bottom wall 32 of the annular connector 3. That is, the second reinforcing plate 31 is provided between the circumferential sidewall of the connecting pipe section 35 and the bottom wall 32 of the annular connector 3. The connecting pipe section 35 passes through the annular connector 3. The second reinforcing plate 31 provided between the circumferential sidewall of the connecting pipe section 35 and the annular connector 3 makes the connection between the connecting pipe section 35 and the annular connector 3 more secure, which is beneficial to a more stable mud transportation process. Alternatively, the second reinforcing plate 31 may not be provided on the circumferential sidewall of the connecting pipe section 35.

[0035] Furthermore, at least two second reinforcing plates 31 are provided, evenly distributed around the circumference of the connecting pipe segment 35. That is, at least two second reinforcing plates 31 are provided, and more may be provided. The second reinforcing plates 31 are distributed in the circumferential direction of the connecting pipe segment 35 and are evenly distributed along the circumferential direction of the connecting pipe segment 35. The number of second reinforcing plates 31 provided between the connecting pipe segment 35 and the annular connector 3 can be arranged according to the actual situation, but at least two are provided. The even distribution of the second reinforcing plates 31 in the circumferential position of the connecting pipe segment 35 is beneficial to the balanced force on the connecting pipe segment 35 and to the firm connection between the connecting pipe segment 35 and the annular connector 3. Alternatively, the second reinforcing plates 31 may be unevenly distributed, and can be arranged at the location where the load of the connecting pipe segment 35 is concentrated, according to the actual situation.

[0036] In optional embodiments, such as Figure 1 As shown, the isolation component 5 is coaxially arranged with the cylinder 2, and the connecting pipe section 35 is connected to the isolation component 5, with the connection position located at the axial center of the cylinder 2. In this application, preferably, the cylinder 2 is cylindrical, which facilitates the winding and release of the slurry pipe. The isolation component 5 is also cylindrical to match the inner wall of the cylinder 2. When the isolation component 5 is coaxially arranged with the cylinder 2, it divides the inner cavity of the cylinder 2 into regularly shaped cavities, which is beneficial for the internal pipe routing of the cylinder 2, reduces pipe bending, and makes slurry transportation smoother. The connection of the connecting pipe section 35 to the isolation component 5 at the axial center of the cylinder 2 means that the connecting pipe is located at the axial center of the cylinder 2. The connecting pipe section 35 is used to transport slurry, and its location at the axial center of the cylinder 2 ensures that the cylinder 2 experiences more uniform stress during slurry transportation. Alternatively, the connecting pipe section 35 and the isolation component 5 may not be coaxial. For example, the isolation component 5 may be perpendicular to the cylinder 2. In this case, the connecting pipe section 35 and the cylinder 2 may also be perpendicular. The guide pipe section on the inlet side of the connecting pipe section 35 may be located at the edge of the cylinder 2 to facilitate the winding of the slurry pipe.

[0037] In addition, this application embodiment also provides a twin-wheel grooving machine, which includes the aforementioned winch. The beneficial effects of the winch on the twin-wheel grooving machine are described above in the relevant description of the winch, and will not be repeated here.
