Description

Technical Field

[0001] This invention relates to the field of excavator component processing equipment technology, and in particular to a tilting device for processing excavator booms. Background Technology

[0002] As a core piece of engineering machinery for infrastructure construction, excavators play an important role in engineering construction. After long-term use, the excavator boom is a key transmission and load-bearing component. During operation, it is constantly scraped and impacted by hard materials such as gravel, sand, and slag. The outer surface of the boom is prone to continuous abrasive wear, and the surface paint and substrate are gradually worn away and peeled off. This not only reduces the appearance integrity of the component, but also gradually weakens the structural strength and deformation resistance of the boom. Furthermore, regarding the front end of the excavator boom, the boom head is the core hinged part that connects the stick pin and transmits the digging force. During operation, the pin and bushing rotate repeatedly relative to each other, and at the same time bear the digging impact force and radial extrusion force. Therefore, under long-term operation, the inner wall of the shaft hole and the mating surface of the pin will experience intermittent wear, scoring and fatigue wear. Since the price of a newly purchased excavator boom is relatively high, it is now more common to carry out repair work on worn and old booms to restore the boom's external dimensions, structural strength and hinge fit accuracy, so that its various performances meet the construction and use standards.

[0003] However, compared to the excavator boom, the excavator's forearm has a more irregular geometry and also has the characteristic of excessive weight. It is not easy to find its dynamic geometric center of gravity during the tilting process. In addition, the forearm's end faces do not have obvious shapes, making it difficult to find a point of sufficient load-bearing. Existing ordinary tilting devices are designed for general-purpose large lifting parts and do not have a specific design to take into account these two characteristics of forearm lifting and tilting. They usually use a crude method of lifting or clamping on both sides for fixation; or fix the front and rear ends of the forearm with pins (i.e., the horse head and the hydraulic cylinder hinge hole). However, because these two holes in old forearms are severely worn, after the pins are inserted into the holes, there is still a gap between the pins and the hole walls. This will cause shaking during the tilting process, which not only affects the operator's processing but also causes secondary damage to the forearm. Furthermore, the existing flipping device uses a pin inserted into the horse head, which prevents the operator from reopening the horse head to repair its internal circumference. The forearm must be removed from the flipping device before the repair operation can be performed inside the horse head. Summary of the Invention

[0004] To address the aforementioned problems, the present invention aims to provide a tilting device for processing excavator booms, which solves the problem that when the boom is fixed on the tilting device, the interior of the boom head is obstructed by the fixed structure, preventing direct processing of the inner wall of the boom head.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: A tilting device for processing excavator booms includes a vertical fixed base installed on the ground, a through slot extending through the fixed base in the left-right direction, a tilting cylinder vertically arranged and rotatably installed in the through slot, two sets of positioning constraint components mirror-symmetrically arranged on the outer left side of the tilting cylinder along the diameter direction for lifting and positioning the boom, a locking component located on the left side of the tilting cylinder and between the two posture constraint components for locking and fixing the boom, and a tilting drive component installed on the fixed base for controlling the rotation angle of the tilting cylinder. Each positioning constraint assembly includes a positioning pin extending along the axis of the hinge hole of the connecting rod in the middle section of the forearm, a connecting seat movably sleeved on the end of the positioning pin away from the center of the tilting cylinder, a fixing frame fixed on the end of the connecting seat away from the center of the tilting cylinder, a control screw coaxially arranged with the positioning pin and movably passing through the side of the fixing frame away from the connecting seat along the axis, a first mounting plate fixed to the connecting seat and detachably mounted on the left outer wall of the tilting cylinder by bolts, and a pair of connecting pieces arranged circumferentially spaced and fixed on the first mounting plate with their free ends fixedly connected to the corresponding side of the connecting seat. Each of the positioning pins has a corresponding connecting seat that extends out from the end away from the center of the rotating cylinder. Each of the control screws has a threaded connection with the positioning pin at the end near the positioning pin, and a threaded connection with the fixing frame at the end away from the positioning pin. The locking assembly includes a second mounting plate detachably mounted on the left outer wall of the tilting cylinder by bolts, a support plate fixed to the left side of the second mounting plate, a pair of fixing members arranged at intervals along the axis of the pin hole of the upper arm in the middle section of the forearm and fixed on the side of the support plate near the center of the tilting cylinder, a pin movably mounted between the two fixing members, two alignment grooves respectively mounted on the ends of the two fixing members near the center of the tilting cylinder and corresponding to the pins, two clamping members corresponding to each fixing member and slidably mounted on the ends of the corresponding fixing members near the center of the tilting cylinder, and two sets of anti-sway components corresponding to each clamping member and mounted between the corresponding clamping member and the fixing member, used to fix and press the pins into the pin hole of the upper arm at the position furthest from the center of the tilting cylinder in the vertical direction. It also includes an auxiliary displacement component mounted on the second mounting plate to assist in guiding the forearm to move and adjust its position and posture in the left and right directions.

[0006] More preferably, each of the positioning pins is fixed with a tapered end extending along the axis of the positioning pin at the end near the center of the rotating cylinder, and the diameter of each tapered end gradually increases from the end near the center of the rotating cylinder to the end away from the center of the rotating cylinder.

[0007] More preferably, each of the control screws has a hand-operated control panel fixed at the end away from the corresponding positioning pin.

[0008] More preferably, each anti-sway assembly includes a wrapping groove provided on the end of the clamping member near the fixing member and covering the outer wall of the pin, and two locking screws provided on the end of the clamping member away from the fixing member and located on the left and right sides of the pin respectively. The lower end of each locking screw extends out of the corresponding clamping member and is close to the fixing member on the side and is threadedly connected to the fixing member.

[0009] More preferably, the auxiliary displacement assembly includes a guide rail that extends in the left-right direction and is fixed to the second mounting plate and whose free end protrudes from the through slot, and a pair of auxiliary rollers that are spaced apart along the length of the pin and rotatably disposed on the free end of the guide rail.

[0010] More preferably, the flipping drive assembly includes a plurality of transmission teeth arranged circumferentially and fixed on the outer wall of the flipping cylinder, a drive gear rotatably disposed on the left outer wall of the fixed seat and meshing with the transmission teeth, a placement platform fixed on the right outer wall of the fixed seat, and a drive motor mounted on the placement platform with its output shaft passing through the fixed seat and axially fixedly connected to the drive gear.

[0011] The present invention has the following beneficial effects: 1. This invention uses two-sided positioning constraint components to insert and fix the connecting rod hinge hole in the middle section of the forearm, and uses a locking component to press and fix the upper arm pin hole in the middle section of the forearm. The fixing point is transferred from the horse head and cylinder hinge hole at the left and right ends of the forearm to the connecting rod hinge hole and upper arm pin hole in the middle section, so that the horse head part at the front end of the forearm is completely exposed without any fixed structure blocking it. The operator can directly perform boring, polishing, welding and other repair processing on the inner wall of the horse head. The repair work of the inner wall of the entire circumference can be completed without disassembling the forearm. This solves the technical problem that the inner wall cannot be processed due to the fixed horse head in the traditional flipping device. 2. The present invention uses two conical ends inserted into the connecting rod hinge hole in the middle section of the forearm through the positioning and constraint components on both sides for constraint and positioning. The pin is fixed and pressed in the locking component on the side of the upper arm pin hole in the middle section of the forearm that is furthest from the center of the rotating cylinder. This can adaptively compensate for the wear gap of the hinge hole, so that the forearm can maintain a stable posture without loosening, offset, or shaking when clamped. 3. The present invention uses an auxiliary displacement component to smoothly place the outer wall of the forearm against the auxiliary roller after the forearm is hoisted into the slot. The forearm is then pushed to the right along the guide track, which greatly reduces the frictional resistance and adjustment difficulty during the installation of the forearm. It also solves the problem that multiple hoisting machines are needed to hoist both ends of the forearm during the process of pushing the forearm to the installation position, which leads to complicated operation and difficult displacement. 4. The center of gravity is specially designed for the shape of the forearm. The locking point is designed on the inner surface of the rotating cylinder, and the raised part (i.e. the physical center of gravity position when the forearm is horizontal) is always kept near the rotating axis of the rotating cylinder, so as to ensure that the center of gravity does not shift when turning 360 degrees.

[0014] The present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments. like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 7As shown, the excavator boom processing tilting device of this embodiment includes a vertical fixed base 1 installed on the ground, a through slot 2 extending through the fixed base 1 in the left and right direction, a tilting cylinder 3 vertically set and rotatably set in the through slot 2, two sets of positioning constraint components 4 mirror-symmetrically arranged on the outer left side of the tilting cylinder 3 along the diameter direction and used for lifting and positioning the boom, a locking component 5 located on the left side of the tilting cylinder 3 and between the two posture constraint components and used for locking and fixing the boom, and a tilting drive component 6 set on the fixed base 1 and used for controlling the rotation angle of the tilting cylinder 3. Each positioning constraint assembly 4 includes a positioning pin 41 extending along the axis of the hinge hole of the connecting rod in the middle section of the forearm, a connecting seat 42 movably sleeved on the end of the positioning pin 41 away from the center of the rotating cylinder 3, a fixing frame 43 fixed on the end of the connecting seat 42 away from the center of the rotating cylinder 3, a control screw 44 coaxially arranged with the positioning pin 41 and movably passing through the side of the fixing frame 43 away from the connecting seat 42 along the axis, a first mounting plate 45 fixed to the connecting seat 42 and detachably mounted on the left outer wall of the rotating cylinder 3 by bolts, and a pair of connecting pieces 46 arranged circumferentially and fixed on the first mounting plate 45 with their free ends fixedly connected to the corresponding side of the connecting seat 42. Each positioning pin 41 is movably protruding from the corresponding connecting seat 42 at the end away from the center of the rotating cylinder 3. Each control screw 44 is threaded to the positioning pin 41 at the end near the positioning pin 41, and threaded to the fixing frame 43 at the end away from the positioning pin 41. The locking assembly 5 includes a second mounting plate 51 detachably mounted on the left outer wall of the tilting cylinder 3 by bolts, a support plate 52 fixed on the left side of the second mounting plate 51, a pair of fixing members 53 arranged at intervals along the axis of the pin hole of the upper arm in the middle section of the forearm and fixed on the side of the support plate 52 near the center of the tilting cylinder 3, a pin 54 movably mounted between the two fixing members 53, two alignment grooves 55 respectively mounted on the end of the two fixing members 53 near the center of the tilting cylinder 3 and corresponding to the pin 54, two clamping members 56 corresponding to each fixing member 53 and slidably mounted on the end of the corresponding fixing member 53 near the center of the tilting cylinder 3, and two sets of anti-sway assemblies 57 corresponding to each clamping member 56 and mounted between the corresponding clamping member 56 and the fixing member 53, used to fix and press the pin 54 into the pin hole of the upper arm at the position furthest from the center of the tilting cylinder 3 in the vertical direction. It also includes an auxiliary displacement component 7, which is mounted on the second mounting plate 51 and is used to assist in guiding the forearm to move in the left and right directions to adjust its position and posture.

[0015] When in use, the auxiliary shifting component 7 supports the forearm and reduces pushing resistance, enabling rapid alignment; the positioning constraint component 4 centers and locks the hinge hole of the connecting rod in the middle section of the forearm through the positioning pin 41, completing radial positioning; the locking component 5 presses the pin against one side of the pin hole of the upper arm, eliminating gaps and preventing shaking; the flipping drive component drives the flipping cylinder to rotate, enabling 360° processing of the forearm without dead angles, and the horse head can be directly repaired without obstruction.

[0016] Because the center of gravity of the forearm is located near the hinge hole of the connecting rod, the axis of the positioning pin 41 in the positioning constraint assembly 4 is set parallel to the diameter of the tilting cylinder 3 in this design. Thus, the hinge hole of the connecting rod in the middle section of the forearm is constrained and fixed on the corresponding central axis of the tilting cylinder by the positioning constraint assembly 4. This ensures that the physical center of gravity of the forearm is always kept near the rotation axis of the tilting cylinder 3 when it is placed horizontally, so that the center of gravity does not shift when the forearm rotates 360 degrees. This also prevents excessive load on the constraint connection due to the shift of the center of gravity during the tilting process, which could cause the connection mechanism to break under pressure.

[0017] like Figure 2 and Figure 3 As shown, each positioning pin 41 is fixed with a tapered end 8 extending along the axis of the positioning pin 41 at one end near the center of the rotating cylinder 3. The diameter of each tapered end 8 gradually increases from the end near the center of the rotating cylinder 3 to the end away from the center of the rotating cylinder 3.

[0018] When in use, the tapered end 8 can automatically wedge into the hinge hole of the forearm connecting rod as the positioning pin 41 is fed. Relying on the tapered surface structure with gradually changing diameter, it adaptively fits the hole wall and compensates for the wear gap of the hole position. It can achieve high-precision automatic centering of the forearm without additional calibration, ensuring that the forearm has no radial movement or circumferential deflection after clamping, and providing a stable and reliable positioning reference for subsequent processing.

[0019] like Figure 1 , Figure 2 , Figure 3 and Figure 7 As shown, each control screw 44 has a hand-operated control panel 9 fixed at the end away from the corresponding positioning pin 41.

[0020] When using this product, the operator can easily rotate the control screw 44 as needed by manually turning the control panel 9.

[0021] like Figure 1 , Figure 2 , Figure 4 and Figure 5As shown, each anti-sway assembly 57 includes a wrapping groove 571 provided on the end of the clamping member 56 near the fixing member 53 and wrapping the outer wall of the pin 54, and two locking screws 572 provided on the end of the clamping member 56 away from the fixing member 53 and located on the left and right sides of the pin 54 respectively. Each locking screw 572 has its lower end protruding from the corresponding clamping part 56 near the fixing part 53 and is threadedly connected to the fixing part 53.

[0022] When using this product, tightening the locking screw 572 causes the clamping part 56 to gradually move closer to the fixing part 53, thereby firmly pressing the pin 54 into the side furthest from the center of the rotating cylinder 3 in the pin hole of the upper arm, eliminating the wear gap between the pin and the hole wall, and achieving complete locking and fixing of the lower arm in the axial and circumferential directions.

[0023] like Figure 1 , Figure 4 and Figure 5 As shown, the auxiliary displacement assembly 7 includes a guide rail 71 that extends and is fixed on the second mounting plate 51 in the left-right direction and has its free end protruding from the through slot 2, and a pair of auxiliary rollers 72 that are spaced apart along the length of the pin 54 and rotatably disposed on the free end of the guide rail 71.

[0024] When using this product, the lifting jaws of the gantry crane are used to clamp the middle section of the forearm, lifting the forearm above the fixed base 1. The right end of the forearm is placed on the guide rail 71. Then, the lifting jaws are removed, and the hook is switched to engage the hydraulic cylinder hinge hole on the left end of the forearm, lifting the left end of the forearm upwards, thereby tilting the entire forearm. Figure 7 As shown, at this time, the lower outer wall of the forearm is placed on the guide rail 71 and abuts against the auxiliary roller 72, greatly reducing the resistance to pushing the forearm to the right, making it easier for the operator to move to the right (i.e., Figure 7 (In the direction of the arrow) Push the forearm to the appropriate position, and after the forearm is installed and locked, due to the structural characteristics of the forearm itself, the outer wall of the forearm is separated from the contact position with the guide rail 71 to prevent long-term pressure on the auxiliary roller 72.

[0025] like Figure 1 , Figure 2 , Figure 6 and Figure 7 As shown, the flipping drive assembly 6 includes several transmission teeth 61 arranged circumferentially and fixed on the outer wall of the flipping cylinder 3, a drive gear 62 rotatably disposed on the left outer wall of the fixed base 1 and meshing with the transmission teeth 61, a placement platform 64 fixed on the right outer wall of the fixed base 1, and a drive motor 63 mounted on the placement platform 64 and whose output shaft passes through the fixed base 1 and is axially fixedly connected to the drive gear 62.

[0026] When using this product, start the drive motor 63 of the flip drive assembly 6, and drive the flip cylinder 3 to rotate as needed through the meshing of the drive gear 62 and the transmission teeth 61. Relying on the stable force transmission and high load capacity of the gear, the forearm can be flipped as needed.

[0027] The working principle of this device is as follows: Step 1: Using the lifting jaws of the gantry crane, clamp the middle section of the forearm and lift it above the fixed base 1. Place the right end of the forearm on the guide rail 71, then remove the lifting jaws and switch to the hook, hooking it into the hydraulic cylinder hinge hole on the left end of the forearm. Lift the left end of the forearm upwards, thereby tilting the entire forearm. Figure 7 As shown, at this time, the lower outer wall of the forearm is placed on the guide rail 71 and abuts against the auxiliary roller 72, greatly reducing the resistance to pushing the forearm to the right, making it easier for the operator to move to the right (i.e., Figure 7 (In the direction of the arrow) Push the forearm to the appropriate position so that the connecting rod hinge hole in the middle section of the forearm is pushed and moved to the position corresponding to the positioning pin 41.

[0028] Step 2: Rotate the hand control disk 9 of the positioning constraint components 4 on both sides to drive the control screw 44 to rotate, push the positioning pin 41 to feed towards the forearm, so that the tapered end 8 is gradually inserted into the connecting rod hinge hole in the middle section of the forearm. Utilizing the self-centering effect of the tapered end 8, the position of the forearm is automatically corrected and it fits tightly against the inner wall of the hinge hole, completing the radial positioning and attitude constraint of the forearm. Then, press down on the left end of the forearm so that the middle section of the forearm abuts against the support plate 52.

[0029] Step 3: Insert the pin 54 into the upper arm pin hole of the forearm, aligning both ends of the pin 54 with the alignment groove 55 of the fixing part 53. Then, fasten the clamping part 56 above the pin 54 and tighten the locking screw 572. The anti-sway assembly 57 firmly presses the pin 54 into the side of the upper arm pin hole furthest from the center of the rotating cylinder 3, eliminating the wear gap between the pin and the hole wall, and achieving complete axial and circumferential locking of the forearm.

[0030] Step 4: After confirming that the forearm is securely clamped, start the drive motor 63 of the flip drive assembly 6. The drive gear 62 meshes with the transmission gear 61 to drive the flip cylinder 3 to rotate as needed, turning the different processing surfaces of the forearm to the operating position. Since the front end of the forearm has no fixed components to block it, the inner wall of the forearm can be directly bored, polished, welded and repaired. After the processing is completed, reverse the above steps to remove the forearm.

[0031] The above description is merely a specific embodiment of the present invention and does not limit the patent scope of the present invention. Any equivalent structural transformations made based on the content of the present invention specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of the present invention.
