Description

Technical Field

[0001] The utility model belongs to the field of construction machinery, and particularly relates to a device for selecting the number of rows of drill pipe boxes of a horizontal directional drill. Background Technique

[0002] The drill pipe loading and unloading device of a small horizontal directional drill generally consists of a drill pipe, a drill pipe box, a drill pipe lifter, a telescopic shuttle arm, a device for selecting the number of rows of drill pipes, etc.

[0003] During the construction of the drill, a certain number of drill pipes matching the drill are pre-installed in the drill pipe box and separated into four rows by partitions in the middle. When the drill works, it is first necessary to determine which row of drill pipes to use and insert a retaining pin into the pin hole corresponding to the number of rows on the shuttle arm. Then, press the control switch of the shuttle arm to retract the shuttle arm below the drill pipe box. The position of the shuttle arm is restricted by the retaining pin so that the gripper in front of the shuttle arm is directly below the drill pipes of the selected row. Then, lower the drill pipes through the drill pipe lifting device so that the gripper in front of the shuttle arm grabs the drill pipes. Finally, move the shuttle arm to send the drill pipes to the power head. When one row of drill pipes is used up, the operator needs to get out of the vehicle to adjust the position of the retaining pin on the shuttle arm to select another row of drill pipes.

[0004] When selecting the number of rows as described above, confirm the number of rows of drill pipes to be used before starting the machine, and then insert a retaining pin at the corresponding position on the shuttle arm. At this time, the shuttle arm is inside the drill, and the operator needs to place part of the body under the drill pipe box. When the number of rows needs to be changed, the drill is in the on state, and the operator still needs to change the position of the retaining pin under the drill pipe box. The above work not only increases the working intensity of the operator, but also is relatively dangerous. Content of the Utility Model

[0005] The purpose of the utility model is to provide a device for selecting the number of rows of drill pipe boxes of a horizontal directional drill, so as to solve the technical problem of danger caused by the need for the operator to manually change the position of the retaining pin when selecting the number of rows of drill pipes.

Specific embodiments

[0046] The present invention will be further described below with reference to the accompanying drawings. The following embodiments are only used to more clearly illustrate the technical solutions of the present invention and should not be used to limit the protection scope of the present invention. Embodiment 1

[0047] Combined with Figure 1 , this embodiment provides a horizontal directional drilling rig drill pipe box column number selection device, which includes:

[0048] A shuttle arm 1, connected with a first driving component, the first driving component is used to drive the shuttle arm 1 to move along a first direction; the first driving component is a gear-rack module, the shuttle arm 1 is connected to the mover of the gear-rack module, and the first driving component can also be other driving parts with the same function in the prior art;

[0049] A telescopic member, fixedly installed on the side of the shuttle arm 1, having a moving stop block 3 that can be telescoped along a second direction, and the second direction is orthogonal to the first direction; the second direction can be horizontal or vertical.

[0050] A positioning block 2, installed on the side of the shuttle arm 1 close to the telescopic member, including a plurality of contact surfaces for abutting against the moving stop block 3 to limit the position of the shuttle arm 1;

[0051] Specifically, the moving stop block is used to extend different lengths and abut against different stepped contact surfaces, so that the shuttle arm 1 is limited at different drill pipe column selection positions. Thus, automatic column number selection can be realized.

[0052] Meanwhile, the selection device in this embodiment further includes: an induction plate 16 or a small induction plate 17 provided on the contact surface of the positioning block 2; and an induction switch 15 provided on the moving stop block 3 through a sensor mounting plate 14 to sense the induction plate 16 of the positioning block 2. When the induction switch 15 senses the induction plate 16 of the positioning block 2, the oil supply to the oil cylinder 5 is stopped, reducing the impact between the positioning block 2 and the moving stop block 3.

[0053] When the extended length of the oil cylinder 5 is different, the moving stop block 3 contacts different contact surfaces of the positioning block 2 or makes the fixed stop block 12 contact the positioning block 2, and the induction switch 15 and the induction plate 16 cooperate to perform induction.

[0054] In this embodiment, the telescopic member includes an oil cylinder 5, and the moving stop block 3 is fixed to the piston rod of the oil cylinder 5.

[0055] In this embodiment, the positioning block 2 has three contact surfaces and three side surfaces, and the number of contact surfaces is the same as the number of drill pipe rows. The distance between two adjacent contact surfaces of the positioning block 2 in the first direction is equal to the column width of each column of drill pipes on the drill pipe box. The distance between two adjacent side surfaces is equal to 1 / 3 of the stroke of the oil cylinder 5. When the positioning block 2 contacts the moving stop block 3 and the fixed stop block 12 for column selection, there is a 4-mm gap between the side surface of the positioning block 2 and the moving stop block 3 to prevent accidental collision.

[0056] It further includes: a bracket 7; an oil cylinder support 10 installed on the bracket 7 for installing the oil cylinder 5; a fixed stop block 12 fixed to the oil cylinder support 10 for, when the moving stop block 3 retracts, abutting against the contact surface of the positioning block 2 to limit the shuttle arm 1 at another drill pipe selection position.

[0057] The selection device in this embodiment further includes: a slide block 11 provided on the oil cylinder support 10 and formed with a chute for slidingly cooperating with the moving stop block 3; a cover plate 13 provided on the slide block 11 and covering above the moving stop block 3 for preventing the moving stop block 3 from deviating out of the slide block 11 under the action of an external force; and a stop pin 4 provided in the chute for fixedly connecting the moving stop block 3 to the piston rod of the oil cylinder 5.

[0058] Specifically, when the oil cylinder 5 is fully retracted, the rightmost side of the moving stop block 3 coincides with the right plane of the slide block 11. When the oil cylinder 5 is fully extended, the moving stop block 3 needs to have sufficient contact area with the slide block 11 to ensure the force on the moving stop block 3. During the telescopic process of the oil cylinder 5, the stop pin 4 always remains in the chute.

[0059] Such as Figure 1As shown, there is a small gap between the movable stop block 3 and the slide block 11. The lateral impact force of the shuttle arm 1 on the movable stop block 3 is transmitted to the oil cylinder support 10 through the slide block 11 and finally acts on the support 7 to avoid impacting the oil cylinder 5.

[0060] The movable stop block 3 and the piston rod of the oil cylinder 5 are connected by a stop pin shaft 4, and there is a large gap to prevent the movable stop block 3 from transmitting the lateral force to the oil cylinder 5. A notch is dug on the outer side where the movable stop block 3 is hinged to the oil cylinder 5, further ensuring that the lateral force of the movable stop block 3 cannot act on the oil cylinder 5, improving the service life of the oil cylinder 5 and preventing the oil cylinder 5 from leaking oil.

[0061] The selection device in this embodiment further includes: an ear plate 8 provided on the oil cylinder support 10, and the oil cylinder 5 is connected to the ear plate 8 through a support pin shaft 9.

[0062] The inner width of the slide block 11 is equal to the inner width of the ear plate 8, which is beneficial to ensuring that the central planes of the ear plate 8 and the slide block 11 coincide. The slide block 11 and the fixed stop block 12 are welded to the oil cylinder support 10 together to reduce the lateral force on the movable stop block 3 and increase the connection reliability.

[0063] The displacement sensor 6 is provided on the telescopic member to monitor the telescopic length of the movable stop block 3. The displacement sensor 66 is built into the oil cylinder 55, reducing the occupied space and improving the measurement accuracy and reliability.

[0064] As Figure 2 shown, when the oil cylinder 5 extends 60 mm, the outermost contact surface of the positioning block 2 contacts the movable stop block 3 to form the selection of the first row of drill pipes. When the oil cylinder 5 extends 40 mm, the middle contact surface of the positioning block 2 contacts the movable stop block 3 to form the selection of the second row of drill pipes.

[0065] As an improvement of the embodiment, as Figure 3 、 Figure 4 shown, the positioning block 2 has three contact surfaces. The innermost contact surface forms the selection of two rows of drill pipes by contacting the movable stop block 3 and the fixed stop block 12. When the oil cylinder 5 extends 20 mm, the innermost plane of the movable stop block 3 and the positioning block 2 contacts to select the third row of drill pipes. When the oil cylinder 5 is fully retracted, the innermost plane of the fixed stop block 12 and the positioning block 2 contacts to select the fourth row of drill pipes. Setting the fixed stop block 12 can reduce the extension length of the oil cylinder 5, reduce the occupied space of the row selection device, and also reduce the lateral impact force generated after the oil cylinder 5 extends, ensuring the service life of the structure.

[0066] The distance between the fixed stop block 12 and the movable stop block 33 is the row width of the drill pipe box, ensuring the accuracy of row selection. To ensure the selection accuracy.

[0067] Furthermore, a cover plate 13 is provided on the slide block 11, which can play a guiding role and ensure that the moving block 3 will not deviate from the slide block 11 under the action of external force, and also has a certain effect of preventing dust and dirt and storing grease. Embodiment 2

[0068] Same as Embodiment 1, the difference between this embodiment and Embodiment 1 is that: as Figure 5 shown, according to the size of the installation space, the drill pipe box row number selection device can be installed perpendicular to the moving direction of the shuttle arm 1, and the positioning block 2 and the moving block 3 can be kept Figure 1 in the form, or the moving block 3 can be changed to a stepped shape.

[0069] In this embodiment, the positioning block 2 and / or the moving block 3 is a stepped structure. The positioning block 2 and / or the moving block 3 is a cylindrical structure, a wedge-shaped structure or a cuboid structure, and the contact surface is a plane or an arc surface.

[0070] As Figure 6 shown, the fixed block 12 can be installed on the shuttle arm 1, and positioning is achieved by the contact between the fixed block 12 and the moving block 3, and the contact surface between the moving block 3 and the positioning block 2 can be a cylindrical surface contact, a plane contact, or a cylindrical surface and plane contact.

[0071] In addition, as Figure 7 shown, both the positioning block 2 and the moving block 3 can be made into a stepped shape, or as Figure 1 shown, one of them can be made into a stepped shape, as long as the number of contact surfaces is the same as the number of rows of the drill pipe box.

[0072] As an improvement in implementation, as Figure 8 shown, the oil cylinder 5 is pin-connected to the moving block 3, and can also be perpendicular to the moving direction of the moving block 3.

[0073] The above are only the preferred embodiments of the present invention. It should be noted that for those of ordinary skill in the art, without departing from the technical principle of the present invention, several improvements and deformations can still be made, and these improvements and deformations should also be regarded as the protection scope of the present invention.
