Description

Technical Field

[0001] This utility model relates to the field of excavator technology, specifically to a connection mechanism for installing a log grapple on an excavator. Background Technology

[0002] A log grapple is an accessory that can be mounted on an excavator, transforming the excavator into a mechanical device capable of grabbing, moving, and stacking logs.

[0003] The prior art discloses a connecting mechanism for installing a log grapple on an excavator, application number CN202220773091.2. This mechanism includes a connecting arm, a pin, a slewing bearing, a grapple arm mounting base, a gripper, and an annular groove. The connecting arm has lugs, and a guide post is vertically mounted on each lug. A floating rod is slidably fitted onto the guide post. Each end of the floating rod has a U-shaped locking block. The floating rod is driven upwards by an elastic abutment, causing the defective portion of the U-shaped locking block to engage with the annular groove. By driving the floating rod upwards through the elastic abutment, the defective portion of the U-shaped locking block engages with the annular groove of the pin, thereby axially limiting the pin and enabling quick pin installation without requiring a lengthy installation process. A chrome plating layer improves the wear resistance of the U-shaped locking block surface, reducing wear. A short pin slides and limits the movement within the slot, preventing the floating rod from detaching from the guide post.

[0004] The floating rod has a U-shaped locking block at each end. When the U-shaped locking block is replaced, the entire device needs to be disassembled, which makes the replacement of the U-shaped locking block more troublesome and requires a lot of time to disassemble. Utility Model Content

Detailed Implementation

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] Please see Figure 1-4 The present invention provides the following technical solution:

[0027] A connecting mechanism for mounting a log grapple on an excavator includes a limiting device 1 and a metal housing 3. A connecting housing 2 is fixedly connected to the bottom of the metal housing 3, and the metal housing 3 is mounted on the surface of the limiting device 1.

[0028] The limiting device 1 includes a connecting block 11, a metal rod 12, a lifting assembly 13, and a metal cylinder 14. The metal rod 12 is slidably connected to the inner wall surface of the metal cylinder 14 and connected to the top of the lifting assembly 13. The metal cylinder 14 is installed at the bottom of the connecting block 11, and the connecting block 11 is installed at the top of the metal housing 3. The metal rod 12 is inserted into the top of the metal housing 3 and slides on the inner wall surface of the metal cylinder 14, allowing it to insert into the metal housing. The top of 3 allows for the movable connection between the metal outer shell 3 and the connecting block 11, facilitating the disassembly and replacement of the metal outer shell 3 and the connecting block 11. The metal cylinder 14 is slidably connected to the top of the inner wall surface of the metal outer shell 3. There are two metal cylinders 14, which are distributed at the left and right ends of the connecting block 11. The metal cylinder 14 is inserted into the bottom of the connecting block 11 and slides on the inner wall surface of the metal outer shell 3, thereby determining the position of the connecting block 11 and facilitating the disassembly and replacement of the connecting block 11.

[0029] The lifting assembly 13 includes a plug-in frame 131, a connecting metal plate 132, a limiting frame 133, a fixing threaded rod 134, an electric push rod 135, a metal plug rod 136, a plug-in housing 137, and a limiting plug-in component 138. The fixing threaded rod 134 is fixedly connected to both sides of the limiting frame 133 and plugged into the inner wall surface of the plug-in housing 137. The plug-in housing 137 is installed on the top of the connecting housing 2, and the limiting plug-in component 138 is plugged into the top of the connecting housing 2. The limiting plug-in component 138 can plug and fix the plug-in housing 137 and the connecting housing 2, facilitating the disassembly and replacement of the plug-in housing 137. The limiting connector 138 is inserted into the bottom of the connector housing 137, which is mounted on the bottom of the metal housing 3. The connector housing 137 is movably connected to both sides of the limiting frame 133, and the connector housing 137 and the limiting frame 133 are movably connected. Simultaneously, the connector housing 137 slides on the surface of the limiting connector 138, allowing the limiting frame 133 and the connector housing 137 to be threadedly fixed. This facilitates the removal of the connector housing 137 from the metal housing 3 and the connecting housing 2, making the replacement of the connector housing 137 quick and convenient. The electric push rod 135 is mounted on the inner wall surface of the limiting frame 133 and connects to the metal plate 132. The electric actuator 135 is installed at the top of the piston rod inside the electric actuator 135, which is installed at the bottom of the metal housing 3. The limiting frame 133 is installed on the inner wall surface of the metal housing 3. The limiting frame 133 can clamp and fix the electric actuator 135, making it easy to disassemble and replace the limiting frame 133 and the electric actuator 135. This makes the replacement of the limiting frame 133 and the electric actuator 135 quick and convenient, and can increase the service life of the limiting frame 133 and the electric actuator 135. The insertion frame 131 is slidably connected to the surface of the metal insertion rod 136, which is slidably connected to the inner wall surface of the metal housing 3. 12 is movably connected to the top of the plug-in frame 131. The second metal plug 136 can drive the plug-in frame 131 to move up and down, which is convenient for adjusting the position of the plug-in frame 131. The first metal plug 12 can be plugged in and fixed to prevent the first metal plug 12 from moving, which can increase the service life of the device. There are two plug-in frames 131, which are distributed front and back. The connecting block 11 can be limited and fixed, which is convenient for disassembling and replacing the connecting block 11. The electric push rods 135 are divided into two groups, with four electric push rods 135 in one group. The four electric push rods 135 on the same side are distributed inside the metal shell 3.

[0030] When in use, the electric push rod 135 is activated, which drives the connecting metal plate 132 to move downward. The connecting metal plate 132 drives the plug frame 131 to move downward through the second metal plug rod 136. The plug frame 131 and the first metal plug rod 12 separate, allowing the first metal plug rod 12 to move back and forth.

[0031] Pull the plug frame 131 outward, and the plug frame 131 moves outward along the surface of the metal plug rod 136. The plug frame 131 can be separated from the metal plug rod 136, making it easy to disassemble and replace the plug frame 131.

[0032] Pushing the metal rod 12 to move back and forth inside the metal cylinder 14 causes the metal rod 12 to slide on the top of the metal casing 3, loosening the connection between the connecting block 11 and the metal casing 3.

[0033] Pulling the connecting block 11 upwards allows it to move along the inner wall surface of the metal casing 3, enabling it to detach from the metal casing 3 and facilitating its disassembly and replacement.

[0034] Then pull the metal rod 136 forward to move it along the inner wall surface of the connecting metal plate 132, so that the metal rod 136 can be detached from the connecting metal plate 132 and can be disassembled and replaced.

[0035] Next, pull the connecting metal plate 132 upward, and the connecting metal plate 132 will disengage from the electric push rod 135, allowing the connecting metal plate 132 to disengage from the electric push rod 135.

[0036] Rotate the nut, and the nut will rotate on the surface of the fixed threaded rod 134, causing the nut to disengage from the fixed threaded rod 134, thereby loosening the connection between the limiting frame 133 and the plug-in housing 137.

[0037] Pulling the limiting connector 138 upwards causes it to disengage from the connector housing 137 and the connecting housing 2. Then, when the connector housing 137 is pulled forward, it slides along the top of the metal housing 3, allowing it to disengage from the connecting housing 2 and making it easy to disassemble and replace.

[0038] Next, pull the limiting frame 133 forward so that the limiting frame 133 slides along the inner wall surface of the metal shell 3, so that the limiting frame 133 disengages from the electric push rod 135, making it easy to disassemble and replace the limiting frame 133, thereby enabling the connecting metal plate 132 and the electric push rod 135 to be replaced or repaired.

[0039] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to the embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
