Description

Technical Field

[0001] The utility model relates to the technical field of well repair, and more specifically, to a guide sliding device of a traveling crane system. Background Art

[0002] The crown block and traveling block of the workover rig are connected with traction wire ropes so that they can move up and down along the height direction of the derrick to form a traveling system. When the conventional workover rig is working, if the traveling block is affected by non-human factors such as wind, it will cause the traveling block to swing greatly, affecting the stability of the operation and endangering the personal safety of the operator. Therefore, it is necessary to explore a safe and reliable traveling block guide sliding device that is easy to install and has strong operational adaptability, so as to ensure the operating stability of the traveling block, improve work efficiency, and improve the safety of personnel operation.

[0003] Existing traveling carriage guiding devices, such as the "stabilizing structure for traveling carriage hook" proposed in Chinese patent CN217354294U, install a fixed frame on the traveling carriage, and the fixed frame moves on the wire rope track to ensure the directional sliding of the traveling carriage, so as to prevent the traveling carriage from swaying left and right due to wind interference. Although it solves the problem of traveling carriage guiding, it still has the following shortcomings: 1) The fixing of the wire rope track requires the installation of a wellhead bracket at the wellhead, which will occupy the wellhead operation space and affect the operation of personnel; 2) The traveling carriage and the fixed frame are connected by a snap connection, and there is a risk of the fixed frame falling off; 3) When the traveling carriage moves up and down, the fixed frame slides on the wire rope track through two parallel pulleys, and the gap between the two pulleys is large, so the stability of the traveling carriage is low when it swings. Utility Model Content

[0029] like Figure 1-4 As shown, the utility model provides a guide sliding device for a traveling crane system, comprising:

[0030] Two ear plates 101 are symmetrically fixed on the crown block 1 and located on both sides of the traveling block 4;

[0031] Two fixing devices are symmetrically arranged on the outer side wall of the lower part of the derrick 2 and are arranged corresponding to the two ear plates 101. Any fixing device is connected to the corresponding ear plate 101 through a wire rope guide rail 3, and the wire rope guide rail 3 is in a straight state;

[0032] The righting frame 5 is slidably arranged on the two wire rope guide rails 3 along the height direction of the derrick 2 , and the traveling block 4 is installed on the righting frame 5 .

[0033] In the above technical solution, if Figure 1 As shown, ear plates 101 are symmetrically installed on both sides of the crown block 1. According to the installation positions of the ear plates 101, two fixing devices are correspondingly installed on the outer side wall of the lower part of the derrick 2. According to the installation positions of the fixing devices, the derrick ear plates can be correspondingly installed on the side walls of the derrick 2. The fixing devices are installed on the ear plates on the side walls of the derrick 2 through pins. A wire rope guide 3 is connected between the fixing devices and the corresponding crown block ear plates 101. The wire rope guide 3 is used for the installation and directional movement of the straightening frame 5. The straightening frame 5 is used for the guiding function of the traveling block 4 to ensure the stable operation of the traveling block 4. When the traveling block 4 is operating, the crown block 1 pulls the wire rope The traveling carriage 4 is driven to move upward / downward, and the straightening frame 5 moves upward / downward along the setting direction of the wire rope guide rail 3. When the traveling carriage 4 is deflected due to interference from external factors, the wire rope guide rails 3 on both sides act on the straightening frame 5 to straighten the traveling carriage 4 in time, so as to realize directional sliding of the traveling carriage 4 during operation and avoid deflection. The wire rope guide rail 3 of the utility model is fixed on the side walls of the crown block 1 and the derrick 2. Compared with the existing traveling carriage guide device, there is no need to install a wellhead bracket at the wellhead, which solves the problem that the wellhead bracket occupies the wellhead operating space and affects the operation of personnel, and the wire rope guide rail 3 can be transported with the vehicle and is easy to disassemble.

[0034] In another technical solution, the uprighting frame 5 comprises:

[0035] The frame 501 is a rectangular frame structure, and a plurality of first pin holes are formed on the frame 501. A plurality of limit plates 401 are provided on the outer wall of the traveling carriage 4. A second pin hole is formed on any limit plate 401. The traveling carriage 4 is sleeved inside the frame 501 and is penetrated through the first pin hole and the second pin hole by a pin, so as to install the traveling carriage 4 on the frame 501.

[0036] Two sets of sliding devices are symmetrically arranged on both sides of the frame 501, and the frame 501 is slidably arranged on the two wire rope guide rails 3 through the two sets of sliding devices.

[0037] In this technical solution, if Figure 3 As shown, the straightening frame 5 includes a frame body 501 and two sets of sliding devices. The frame body 501 is used to connect the straightening frame 5 with the traveling carriage 4, and the sliding device is used to connect with the wire rope guide rail 3. The traveling carriage 4 and the frame body 501 are fixed by a pin shaft, which ensures the stability of the connection between the traveling carriage 4 and the straightening frame 5. Compared with the existing traveling carriage guide device, the risk of the straightening frame 5 falling off is avoided.

[0038] In another technical solution, the first pin shaft hole is opened on the top surface of the frame 501 , and a plurality of the limit plates 401 are arranged at intervals along the outer circumference of the traveling carriage 4 , and any limit plate 401 is horizontally placed on the top surface of the frame 501 .

[0039] In the present technical solution, when the traveling car 4 is connected to the straightening frame 5, the traveling car 4 can be directly erected on the frame 501 through the limit plate 401, and then the pin shaft can be installed from the top surface of the frame 501 to facilitate the connection between the traveling car 4 and the straightening frame 5; and the outer periphery of the traveling car 4 is erected in the frame 501 through a plurality of limit plates, which ensures the horizontality of the traveling car 4 on the straightening frame 5 and the accuracy of subsequent operations.

[0040] In another technical solution, any group of sliding devices includes a side plate 502, which is fixedly arranged on the outer wall of the frame 501 along the height direction of the derrick 2, and two pulley groups are arranged on the inner wall of any side plate 502, which are symmetrically arranged along the height direction of the derrick 2. Any pulley group includes two staggered first pulleys 503 and second pulleys 504, and the wire rope guide rail 3 is inserted into the gap between the first pulley 503 and the second pulley 504.

[0041] In this technical solution, if Figure 4 As shown, four pulleys are arranged on the side plate 502 of the straightening frame 5, and the pulleys are staggered and symmetrically arranged in pairs. The gap between the two adjacent first pulleys 503 and second pulleys 504 is small, and the wire rope guide rail 3 is inserted in the gap, which can further ensure the guiding performance of the wire rope guide rail 3 and ensure the stability of the traveling carriage 4 when it swings.

[0042] In another technical solution, Figure 2 As shown, the fixing device includes a basket bolt 7, one end of which is connected to the outer wall of the derrick 2, and the other end is connected to the end of the wire rope guide rail 3.

[0043] In the present technical solution, one end of the flower basket bolt 7 can be detachably mounted on the ear plate on the outer wall of the derrick 2 through a pin shaft. The flower basket bolt 7 is used to ensure that the wire rope guide rail 3 is in a taut state. After one end of the wire rope guide rail is connected to the corresponding overhead crane ear plate 101, the other end is passed through the gap between the first pulley 503 and the second pulley 504 and then connected to the flower basket bolt 7. By adjusting the flower basket bolt 7 to a straight state, the directional guiding function of the wire rope guide rail 3 is ensured.

[0045] In the present technical scheme, the pulley bracket 6 is rotatably connected to the ear plate on the outer side wall of the derrick 2. On the one hand, it is used for directional guiding of the wire rope guide rail 3. Specifically, when the traveling carriage is operating, the pulley bracket 6 is first adjusted to a horizontal state, and then the third pulley 601 is rotated to adjust the direction of the wire rope guide rail 3, so that the wire rope guide rail 3 is in a state vertical to the ground, and in the operating range where the traveling carriage 4 moves up and down, it is ensured that the traveling carriage is facing the center of the wellhead when operating; on the other hand, after the operation is completed and the traveling carriage 4 is left, the pulley bracket 6 can be adjusted to a state vertical to the ground. At this time, the wire rope guide rail 3 will be close to the outer side wall of the lower part of the derrick 2, thereby reducing the installation and fixing space of the wire rope guide rail 3; a first positioning hole and a second positioning hole can be opened on the ear plate of the outer side wall of the derrick 2. When the pulley bracket 6 is connected to the first positioning hole through a pin shaft, the pulley bracket is in a horizontal state, and when connected to the second positioning hole, it is in a state vertical to the ground.

[0046] Although the implementation scheme of the utility model has been disclosed as above, it is not limited to the applications listed in the specification and implementation modes. It can be fully applied to various fields suitable for the utility model. For those familiar with the art, additional modifications can be easily implemented.
