Description

Technical Field

[0001] The utility model relates to a high-performance low-temperature-resistant traveling cable for a drilling top drive device, belonging to the technical field of electric cable processing. Background Art

[0002] Currently, top drive systems used in oilfields typically consist of three components: an electrical control room located on the surface, the top drive body mounted on the derrick, and the top drive cable. The top drive cable is further divided into two parts: the power cable, which transmits power, and the control cable, which transmits signals. Due to the long transmission distances, the power cable is generally divided into three sections based on its location in use for ease of installation and transportation: the traveling cable, the derrick cable, and the ground cable.

[0003] During operation, the top drive body needs to move back and forth up and down on the derrick, and one end of the traveling cable will also move with the top drive body. Therefore, the traveling cable near the top drive body is easily damaged. In low temperature environments, the cable will lose its elasticity, crack and break, and cannot withstand repeated movement or bending. The conductor will leak out, posing a safety hazard and having a short service life. Utility Model Content

[0004] Based on the above background, the purpose of the present invention is to provide a high-performance low-temperature-resistant traveling cable for a drilling top drive device to solve the problems described in the background technology.

[0005] In order to achieve the above-mentioned purpose of the utility model, the utility model provides the following technical solutions:

[0006] A high-performance, low-temperature-resistant traveling cable for a drilling top drive device comprises an outer sheath, a protective component is arranged on the outside of the outer sheath, a first pressure-resistant block and a second pressure-resistant block are respectively arranged inside the outer sheath, and cables are installed inside the first and second pressure-resistant blocks.

[0007] Preferably, the protective assembly includes a first protective plate and a second protective plate arranged on the outside of the outer sheath, and a plurality of elastic plates are arranged on the inner walls of the first protective plate and the second protective plate. An elastic block is arranged on the top of the elastic plate, and an inner sheath is arranged on the top of the elastic block. The inner sheath is arranged in a semicircular shape.

[0008] Preferably, the protective assembly further comprises mounting plates arranged on both sides of the first protective plate and the second protective plate, wherein screws are threadedly connected in the mounting plates.

[0009] Preferably, positioning blocks are provided on the outside of the first anti-compression block and the second anti-compression block, and positioning grooves for use with the positioning blocks are provided inside the outer sheath.

[0010] Preferably, a mounting groove is provided inside the positioning block, and a fixing bolt is provided inside the mounting groove.

[0011] Preferably, a threaded hole for use with a fixing bolt is provided inside the positioning block.

[0012] Preferably, a plurality of insertion rods are provided on both sides of the bottom of the first anti-pressure block, and a slot for use with the insertion rods is provided on the top of the second anti-pressure block.

[0013] Compared with the prior art, the utility model has the following advantages:

[0014] 1. The first and second anti-compression blocks provide preliminary protection for the exterior of the cable. The outer sheath is installed outside the first and second anti-compression blocks to further protect the internal cable and improve the compressive strength of the cable when it moves or bends. When the outer and inner sheaths are squeezed or bent, the pressure is transmitted to the elastic plate and the elastic block, causing them to deform under pressure and dissipate the pressure. After the pressure dissipates, the elastic plate and the elastic block return to their initial positions, thereby enhancing the cable's anti-bending performance and preventing the cable from breaking when squeezed or bent.

[0015] 2. Insert the positioning block into the positioning groove to position the first anti-compression block and the second anti-compression block to prevent them from being entangled under force. Insert the insertion rod into the slot to install and position the first anti-compression block and the second anti-compression block to improve their stability. BRIEF DESCRIPTION OF THE DRAWINGS
