Description

Technical Field

[0001] The invention belongs to the technical field of cable installation, and in particular relates to a cable bridge auxiliary installation device. Background Art

[0002] Cable trays, as a structural system, are primarily used to support and protect wires, cables, and related accessories. To enhance cable tray flexibility, modern design trends favor modularization, allowing for easy assembly and splicing. To further simplify this process, specialized cable tray installation aids have emerged on the market. However, in practical applications, these devices have exposed several issues:

[0003] First, current cable tray installation methods primarily include horizontal single-hang, horizontal double-hang, horizontal against a wall, and vertical against a wall. Most auxiliary equipment is designed for horizontal installation and lacks support for other installation methods, impacting construction efficiency and quality. This is especially true when installing cable trays in multiple layers or rows, where existing equipment struggles to provide adequate support, increasing construction difficulty and safety risks.

[0004] Secondly, existing bridge auxiliary installation equipment mainly relies on support platforms to support and fix the bridge. This design provides stable support during horizontal installation and ensures smooth construction. However, when facing inclined or vertical installation, traditional support components may not be able to adapt to the new angle and lack sufficient support force, which complicates the installation process and increases construction difficulty and time costs.

[0005] Finally, in addition to the support platform, rigid clamps located on the outside of the bridge are often used to assist in bridge installation. Since the bridge itself is a hollow structure, rigid clamps typically secure it by tightening bolts or applying pressure in other ways. This direct pressure can lead to uneven localized force, causing bending or denting of the bridge material. Furthermore, direct contact between the clamp and the bridge surface can also cause scratches or other damage due to friction, especially during repeated adjustment or disassembly.

[0006] In summary, the existing bridge auxiliary installation equipment has installation method limitations, challenges in tilted and vertical installation, and the risk of damaging bridge materials during the actual bridge assembly process. Summary of the Invention

[0007] In view of this, an object of the present invention is to provide a cable tray auxiliary installation device to solve the problems existing in the above-mentioned background technology.

[0008] In order to solve the above technical problems, the first technical solution of the present invention is a cable tray auxiliary installation device, wherein the cable tray is composed of a tray and a cover plate, and the tray is composed of a bottom plate and a side plate; the characteristic is that the installation device includes a lifting assembly, the lifting assembly is arranged on both sides of the width direction of the tray, and the lifting assembly acts on the bottom plate of the tray; the lifting assembly is provided with a clamping assembly on both sides along the length direction of the tray, and the clamping assembly acts on the side plate of the tray; the clamping assembly includes a clamping member, the clamping member is located on the inner and outer sides of the tray, and the clamping member is pneumatically controlled, and the clamping member is moved by introducing gas and acts on the inner and outer sides of the side plate of the tray, thereby realizing the installation and fixation of the cable tray. The use of pneumatic control improves the degree of automation of the installation equipment while making it lighter, and uses gas to avoid the shaking that is inevitable in the assembly of the cable tray, thereby improving the stability of the cable tray installation.

[0013] Furthermore, the state of the clamping assembly is changed by a flipping assembly: the installation device also includes a flipping assembly located between the lifting assembly and the clamping assembly, and the flipping assembly can switch the clamping assembly between a deployed state and a clamping state; when the clamping assembly is in the deployed state, the clamping member is parallel to the bottom plate of the pallet, so that the clamping assembly can reach above the pallet, and the clamping assembly is switched to the clamping state by the flipping assembly, so that the clamping member in the clamping assembly can act on the inner and outer sides of the pallet side plate, thereby realizing the installation and fixation of the bridge frame.

[0015] Furthermore, the tilt angle of the lifting assembly is changed by adjusting the assembly: the installation device also includes an adjusting assembly, which is used to adjust the tilt angle of the lifting assembly to facilitate the assembly of the slope end bridge; the adjusting assembly includes a first lifting rod and a second lifting rod connected to the lifting assembly, and the tilt angle of the lifting assembly is changed by adjusting the length of the first lifting rod and the second lifting rod; the bottom end of the first lifting rod and the bottom end of the second lifting rod are both connected to the mounting plate.

[0016] Furthermore, the installation equipment is optimized for assembling bridge frames of different widths: the lifting assembly, the clamping assembly and the adjusting assembly located on the same side of the width direction of the pallet constitute a fixing module, and the fixing modules on both sides of the width direction of the pallet are respectively a first fixing module and a second fixing module; at least one of the first fixing module and the second fixing module is arranged on the moving end of a linear moving assembly, and the transmission direction of the linear moving assembly is parallel to the width direction of the pallet; the distance between the first fixing module and the second fixing module is controlled by the linear moving assembly, so that the installation equipment is suitable for assembling bridge frames of different width specifications.

[0018] The technical effects of the present invention are mainly reflected in the following aspects:

[0019] The lifting assembly and flip assembly design of the present invention enables the equipment to flexibly adapt to different installation methods (horizontal single hanging, horizontal double hanging, horizontal against the wall, vertical against the wall), especially when laying multiple layers or multiple columns of bridge frames, providing higher flexibility; the detachable connection design between the first lifting rod and the second lifting rod and the lifting assembly enables the equipment to be quickly adjusted to a vertical wall installation mode to meet the needs of different scenarios; through the linear moving components in the width and length directions, the equipment can accurately adjust the position of the fixed module, which is suitable for the assembly of bridge frames of different widths and lengths.

[0032] The specific embodiments of the present invention are further described below in conjunction with the accompanying drawings to make the technical solutions of the present invention easier to understand and grasp.

[0033] In this embodiment, it should be understood that the terms "middle", "upper", "lower", "top", "right", "left end", "above", "back", "middle", etc., indicating the orientation or position relationship, are based on the orientation or position relationship shown in the accompanying drawings, and are only for the convenience of describing the present invention, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present invention.

[0034] In addition, in this specific embodiment, if the connection or fixing method between components is not specifically described, the connection or fixing method can be through bolt fixing or pin fixing, or pin shaft connection, etc. commonly used in the prior art, so it will not be described in detail in this embodiment.

[0035] To facilitate the functional description of the cable tray auxiliary installation equipment of the present invention, the structural composition of the tray is now introduced: the tray is composed of a tray and a cover plate. The tray is also called the tray body, which mainly serves as a support platform for the cable; the cover plate is used to protect the cable from the influence of the external environment, such as dust, moisture or other potential hazards; among them, the tray can be divided into a straight section, an elbow, and a slope section (also called an inclined section divided into an ascending section, a descending section and an inclined elbow), and the tray is composed of a bottom plate and a side plate; the above descriptions are all common knowledge of the technical personnel in this field about the composition of the tray structure.

[0036] To facilitate the functional description of the auxiliary installation equipment of the cable tray 1 of the present invention, the structural composition of the tray 1 is now introduced: the tray 1 is composed of a tray and a cover plate. The tray is also called the tray 1 body, which mainly serves as a support platform for the cable; the cover plate is used to protect the cable from the influence of the external environment, such as dust, moisture or other potential hazards; among them, the tray can be divided into a straight section, an elbow, and a slope section (also called an inclined section divided into an ascending section, a descending section and an inclined elbow), and the tray is composed of a bottom plate and a side plate; the above descriptions are all common knowledge of the technical personnel in this field about the structural composition of the tray 1.

[0037] Example 1

[0038] See also Figure 1 This embodiment discloses an auxiliary installation device for a cable tray 1, wherein the tray 1 is composed of a tray and a cover plate, and the tray is composed of a bottom plate and a side plate; the characteristic is that the installation device includes a lifting assembly 2, and the lifting assembly 2 is arranged on both sides of the tray in the width direction, and the lifting assembly 2 acts on the bottom plate of the tray; the lifting assembly 2 is provided with a clamping assembly 3 on both sides along the length direction of the tray, and the clamping assembly 3 acts on the side plates of the tray; the clamping assembly 3 includes a clamping member 31, and the clamping member 31 is located on the inner and outer sides of the tray, and the clamping member 31 is pneumatically controlled, and the clamping member 31 is moved by passing gas, and acts on the inner and outer sides of the tray side plates, thereby achieving the installation and fixation of the tray 1. Specifically, traditional rigid clamps are prone to damage to the material of the tray 1, and may cause local uneven force in the hollow structure. This embodiment introduces pneumatically controlled clamps 31, which are located on the inner and outer sides of the tray side plates. When gas is introduced, the clamping member 31 will move evenly inward or outward, applying uniform pressure to the side panels of the pallet, thus avoiding the problem of local stress concentration caused by traditional clamps. At the same time, because the pneumatic system can respond quickly, it improves the degree of automation of the installation process, making the installation lighter and more stable. Furthermore, in order to avoid scratches or other damage caused by direct contact between the clamping member 31 and the surface of the bridge 1, a special anti-slip and protective coating is applied to the contact surface of the clamping member 31. This coating not only increases friction and prevents the bridge 1 from sliding during installation, but also effectively protects the surface of the bridge 1 from scratches, and is particularly suitable for situations where repeated adjustment or disassembly is required.

[0039] See also Figure 3 、 Figure 4The lifting assembly 2 comprises a bracket 21 with an L-shaped end face, and a mounting cavity 22 is formed at the bottom bending part of the bracket 21, and a movable block 23 is arranged in the mounting cavity 22; the position of the movable block 23 in the mounting cavity 22 is controlled by introducing gas into the mounting cavity 22, so as to control the length of the bottom of the bracket 21.

[0040] Specifically, when the horizontal wall-relying and multi-layer bridge 1 is installed, the adjustable bracket 21 design can pass through the gap of the bridge, that is, the bottom of the bracket 21 can be stretched or retracted according to the actual situation to adapt to the requirements of different layer spacings. This not only improves the flexibility of installation, but also reduces the safety hazards caused by the mismatch of installation gaps; after the bracket 21 passes through the gap to the specified height, the bracket 21 can be stretched to better lift the bridge 1 with a larger width.

[0041] Referring to Figure 3 , Figure 5 The clamping piece 31 comprises a vertical rod 32, and a first air bag 33 is wrapped around the outer periphery of the vertical rod 32, and the vertical rod 32 serves as the structural support of the clamping piece 31; the stability and positioning accuracy of the air bag during inflation are ensured. The vertical rod 32 is usually made of high-strength materials such as aluminum alloy or stainless steel to withstand large clamping forces without deformation. The first air bag 33 is inflated and deflated by a separate pneumatic control system. When it is necessary to fix the bridge 1, an external gas source (such as a compressed air tank or an air pump) will introduce gas into the first air bag 33 to make the air bag expand. By introducing gas into the first air bag 33, the first air bag 33 is inflated, and the first air bag 33 acts on the tray side plate to achieve the installation and fixation of the bridge 1; after the air bag is inflated, its surface is uniformly attached to the inner and outer sides of the tray side plate, providing stable support force. Since the air bag is soft and deformable, it can automatically adjust the contact surface according to the shape of the side plate, ensuring uniform pressure distribution and avoiding the local stress concentration problem that may be caused by traditional rigid clamps.

[0042] Referring to Figure 3 , Figure 8, the mounting device further comprises a turnover assembly 4 between the lifting assembly 2 and the clamping assembly 3, which can switch the clamping assembly 3 between the deployment state and the clamping state; when the clamping assembly 3 is in the deployment state, the clamping pieces 31 are parallel to the bottom plate of the tray, so that the clamping assembly 3 can reach above the tray, and the clamping assembly 3 is switched to the clamping state by the turnover assembly 4, so that the clamping pieces 31 in the clamping assembly 3 can act on the inner and outer sides of the side plate of the tray, thereby realizing the mounting and fixing of the bridge 1. The turnover assembly 4 comprises a connecting piece 41 connecting the clamping assembly 3 and the lifting assembly 2 together and responsible for transmitting power to realize the state switching of the clamping assembly 3. The connecting piece 41 is provided with a turnover seat 42 on both sides along the length direction of the tray, the turnover seat 42 is provided with an arc-shaped cavity 43 inside, and the arc-shaped cavity 43 is provided with a piston block 44. The design of the arc-shaped cavity 43 enables the piston block 44 to perform circumferential motion therein, thereby driving the clamping assembly 3 to rotate. The turnover seat 42 is provided with an external window 45 on both sides along the width direction of the tray, and the piston block 44 is connected with the clamping piece 31 through the external window 45. The movement of the piston block 44 directly determines the rotation angle and position of the clamping assembly 3. By introducing gas into the arc-shaped cavity 43, the position of the piston block 44 in the arc-shaped cavity 43 is pushed, thereby driving the clamping assembly 3 to rotate and realizing the switching of the clamping assembly 3 between the deployment state and the clamping state.

[0043] Specifically, by introducing gas (such as compressed air) into the arc-shaped cavity 43, the pressure of the gas will push the piston block 44 to move in the arc-shaped cavity 43. According to the pressure of the gas introduced, the piston block 44 can perform predetermined circumferential motion in the arc-shaped cavity 43. When the gas is introduced, the piston block 44 is pushed, driving the clamping assembly 3 to gradually turn from the deployment state to the clamping state; on the contrary, when the gas is extracted, the piston block 44 returns to the original position, and the clamping assembly 3 recovers from the clamping state to the deployment state.

[0044] Referring to Figure 3 , Figure 9 , Figure 10, the mounting device further comprises an adjusting assembly 5 for adjusting the inclination angle of the lifting assembly 2 to facilitate the assembly of the ramp end bridge 1; the adjusting assembly 5 comprises a first lifting rod 51 and a second lifting rod 52 connected with the lifting assembly 2, and the bottom ends of the first lifting rod 51 and the second lifting rod 52 are connected to the mounting plate. The first lifting rod 51 and the second lifting rod 52 are respectively connected with the two ends of the lifting assembly 2. Each lifting rod is composed of an inner rod and an outer rod, the inner rod can slide up and down in the outer rod, and is fixed at the required position by a locking mechanism. The inclination angle of the lifting assembly 2 is changed by adjusting the length of the first lifting rod 51 and the second lifting rod 52. The connection between the first lifting rod 51 and the lifting assembly 2 and the connection between the second lifting rod 52 and the lifting assembly 2 are both detachable connections, and the quick connector is usually composed of a latch, a locking nut or a buckle, etc., which allows the construction personnel to complete the connection and disassembly of the lifting rod and the lifting assembly 2 within a short time. A plurality of positioning holes are arranged on the lifting assembly 2, and the end of the lifting rod is provided with a corresponding pin. When connection is needed, the pin is inserted into the positioning hole, and is fixed by a locking device (such as a nut or a buckle); when disassembly is needed, the locking device is loosened and the pin is pulled out; in some application scenarios, a magnetic connection method can also be used. Strong magnets are embedded on the lifting assembly 2 and the lifting rod respectively, and when connected, they are automatically attracted by magnetic force, and when disassembled, only the magnetic force needs to be overcome. This method not only has simple operation, but also can ensure the stability of the connection. When vertical installation against the wall is needed, the construction personnel can easily disassemble the connection between the first lifting rod 51 or the second lifting rod 52 and the lifting assembly 2. After disassembling the connection, the bottom plate of the lifting assembly 2 can be parallel to the first lifting rod 51 and the second lifting rod 52, forming a plane perpendicular to the wall surface. At this time, the lifting assembly 2 can be directly installed against the wall to ensure the stability and safety of the bridge 1. After completing the vertical installation, if it is needed to restore the horizontal installation mode, the construction personnel can reconnect the lifting rod and the lifting assembly 2 according to the reverse steps to restore the original support structure.

[0045] Referring to Figure 1 、 Figure 2, the lifting assembly 2, the clamping assembly 3 and the adjusting assembly 5 on the same side of the width direction of the tray form a fixed module, which works cooperatively to provide all-round support and fixation for the bridge 1. The fixed module adopts a modular design concept, and each component (such as the lifting assembly 2, the clamping assembly 3 and the adjusting assembly 5) can be independently replaced or upgraded according to actual needs, thereby reducing maintenance costs and improving the versatility of the equipment. The fixed modules on both sides of the width direction of the tray are respectively a first fixed module 61 and a second fixed module 62. At least one of the first fixed module 61 and the second fixed module 62 is provided with a moving end of a linear movement assembly, and the transmission direction of the linear movement assembly is parallel to the width direction of the tray. The distance between the first fixed module 61 and the second fixed module 62 is controlled by the linear movement assembly, so that the installation equipment is suitable for assembling bridge 1 of different width specifications. The linear movement assembly includes a guide rail parallel to the width direction of the tray and at least one moving end. The moving end can slide along the guide rail in a straight line to drive the first fixed module 61 or the second fixed module 62 to move. The guide rail is usually made of high-strength materials such as aluminum alloy or stainless steel to ensure its carrying capacity and wear resistance. The first fixed module 61 and the second fixed module 62 are located on both sides of the width direction of the tray and are responsible for bilateral support and fixation of the same section of the bridge 1. The first fixed module 61 and the second fixed module 62 are also provided with a third fixed module 63 and a fourth fixed module 64 along the length direction of the tray, and the third fixed module 63 and the fourth fixed module 64 are respectively used for fixation of adjacent sections of the bridge 1. The four fixed modules work together to ensure the stable connection and precise docking between multiple sections of the bridge 1. The first fixed module 61 and the second fixed module 62 and the third fixed module 63 and the fourth fixed module 64 are respectively used for fixation of different trays to realize the assembly and docking of the bridge 1. In addition to the original width direction linear movement assembly, the newly added third fixed module 63 and the fourth fixed module 64 are also equipped with a length direction linear movement assembly. The transmission direction of these linear movement assemblies is parallel to the length direction of the tray, which can accurately control the position of the third fixed module 63 and the fourth fixed module 64. By combining the width direction and length direction linear movement assemblies, the positions of the four fixed modules can be flexibly adjusted to ensure that they can accurately align and fix different sections of the bridge 1. The dual-axis control system can be remotely operated by intelligent devices, improving the convenience and accuracy of operation.

[0046] Embodiment two

[0047] Reference Figure 3 , Figure 6This embodiment discloses an auxiliary installation device for a cable tray 1. Compared with the installation device in the first embodiment, the installation device in this embodiment upgrades the structure of the clamping member 31 as follows:

[0048] The clamping member 31 includes a fixed plate 34 and a movable plate 35. A multi-stage telescopic structure 36 is provided between the fixed plate 34 and the movable plate 35. The fixed plate 34 serves as a structural support for the clamping member 31. The fixed plate 34 is usually made of a high-strength material (such as aluminum alloy or stainless steel) to ensure that it does not deform when subjected to a large clamping force. The fixed plate 34 is connected to the lifting assembly 2 or other fixed structure to provide a stable base for the entire clamping member 31; the movable plate 35 is located opposite the fixed plate 34 and can move along the axis of the multi-stage telescopic structure 36. The design of the movable plate 35 can be adjusted according to the specific shape of the side panel of the pallet to ensure that it can fit closely to the surface of the side panel and provide a uniform clamping force. By introducing gas into the multi-stage telescopic structure 36, the multi-stage telescopic structure 36 is driven to extend, so that the movable plate 35 is moved, so that the movable block 23 acts on the side panel of the pallet to achieve the installation and fixation of the bridge frame 1.

[0049] Specifically, the multi-stage telescopic structure 36 can be composed of multiple retractable cylinders. The combined action of these cylinders allows the movable plate 35 to be fine-tuned at different positions to accommodate varying clamping requirements. Numerous similar structures for the multi-stage telescopic structure 36 have been published online, so we will not elaborate on them here.

[0050] Example 3

[0051] See also Figure 3 、 Figure 7 This embodiment discloses an auxiliary installation device for a cable tray 1. Compared with the installation devices in the first and second embodiments, the installation device in this embodiment upgrades the structure of the clamping member 31 as follows:

[0052] The clamping member 31 includes a fixed plate 34 and a movable plate 35. A return spring 37 and a second air bag 38 are provided between the fixed plate 34 and the movable plate 35. The fixed plate 34 serves as a structural support for the clamping member 31. By introducing gas into the second air bag 38, the second air bag 38 is expanded, and the movable plate 35 is moved, so that the movable block 23 acts on the side plate of the pallet to achieve the installation and fixation of the bridge frame 1. When the gas in the second air bag 38 is discharged, the return spring 37 will automatically push the movable plate 35 back to the initial position, ensuring that the clamping member 31 is in a relaxed state when not in use. During the clamping process, the return spring 37 can absorb part of the impact force, prevent the movable plate 35 from exerting excessive pressure on the side plate of the pallet, and protect the surface of the bridge frame 1 from damage.

[0053] The effects of the clamping member 31 are compared as follows:

[0054] The clamping member 31 in Example 1: The airbag can automatically adjust the contact surface according to the shape of the pallet side panel, ensuring that the clamping force is evenly distributed and avoiding local stress concentration; at the same time, the airbag is soft and deformable, reducing the direct pressure on the pallet side panel, and effectively protecting the surface of the bridge frame 1 from scratches or other damage; moreover, the airbag can adapt to pallet side panels of different shapes and sizes, thereby improving the versatility and flexibility of the equipment.

[0055] The multi-stage telescopic structure 36 of the clamping member 31 in Example 2 allows for graded control of the movable plate 35 at different stages, ensuring a gradual increase in clamping force and avoiding sudden excessive pressure. Furthermore, the movement distance of the movable plate 35 can be precisely adjusted by controlling the gas flow and pressure, enabling fine-tuning of the clamping force, making it suitable for installations requiring high precision. Furthermore, the movable plate 35 can be adjusted to the specific shape of the pallet side panels, ensuring a tight fit and providing stable support.

[0056] The clamping member 31 in Example 3: A return spring 37 automatically returns the clamping member 31 to its initial position when not in use, simplifying the operation process and improving the device's usability. Furthermore, the return spring 37 acts as a buffer during the clamping process, preventing the movable plate 35 from exerting excessive pressure on the pallet side panels and protecting the surface of the bridge 1 from damage. The second airbag 38 allows for fine-tuning of the movable plate 35 in different positions, ensuring even distribution of the clamping force on the pallet side panels and avoiding localized stress concentration.

[0057] Example 4

[0058] This embodiment discloses an auxiliary installation device for a cable tray 1. Compared with the installation device in the first embodiment, this embodiment further optimizes the structure of the flip assembly 4 in the installation device, as follows:

[0059] The piston block 44 of the flip assembly 4 in the first embodiment has only one end connected to the arc cavity 43 and the other end is exposed. The piston block 44 can only perform a predetermined circular motion in the arc cavity 43 by introducing or extracting gas into the arc cavity 43.

[0060] In this embodiment, both ends of the piston block are closed and are completely sealed and connected to the arc cavity 43. This design not only improves the sealing of the piston block 44 in the arc cavity 43, but also reduces the possibility of gas leakage, ensuring the efficiency of the gas drive. Since both ends of the piston block 44 are closed and completely sealed and connected to the arc cavity 43, the efficiency of the gas drive is higher and the response speed of the piston block 44 is faster. When the gas is introduced from one side, the piston block 44 is pushed to the other side, driving the clamping assembly 3 to gradually turn from the deployed state to the clamping state; conversely, when the gas is introduced from the other side, the piston block 44 returns to its original position, and the clamping assembly 3 returns from the clamping state to the deployed state. This process is fast and smooth, ensuring the accurate switching of the clamping assembly 3.

[0061] In addition, as common knowledge in the industry, the first lifting rod 51, the second lifting rod 52, the multi-stage telescopic structure 36, and the first airbag 33 and the second airbag 38 mentioned above, the installation equipment in the attached figure is also equipped with a lifting frame, the above is common knowledge; therefore, its principle and structure will not be described in detail.

[0062] Of course, the above are only typical examples of the present invention. In addition, the present invention may also have many other specific implementation methods. Any technical solutions formed by equivalent replacement or equivalent transformation fall within the scope of protection required by the present invention.
