Description

Technical Field

[0001] This invention relates to the field of concrete pouring and lining trolley technology, specifically a large arch structure construction lining trolley. Background Technology

[0002] In the construction of open tunnels, tunnels, and various types of ground-level arched concrete structures, lining construction trolleys are key construction equipment for achieving concrete lining formation and ensuring structural dimensions and construction quality. To address the issues of insufficient positioning accuracy and operational safety during the movement and positioning of lining construction trolleys, several conventional solutions have been developed in existing engineering practices, but these still have varying degrees of limitations in practical application.

[0003] One approach involves supplementing manual operation with simple mechanical or passive auxiliary measures, such as setting travel limits, strengthening braking devices, or taking temporary fixing measures after stopping, to reduce the risk of unexpected movement of the trolley. This approach can alleviate the slippage phenomenon to some extent, but the poor braking effect still cannot solve the problem of precise positioning during the trolley's movement. Therefore, we have introduced a large arched structure construction lining trolley. Summary of the Invention

[0004] The purpose of this invention is to provide a large-scale arch structure construction lining trolley to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution:

The hydraulic rail clamping moving components include a sliding base, a sliding moving seat with the front and rear ends of the bottom of the sliding base connected by a moving hydraulic cylinder, and a rail clamping component set on the sliding moving seat.

[0008] The pulley inside the sliding base sits on the sliding track. The upper front and rear ends of the sliding base are provided with limiting reinforcement members that are fixed to the lower end of the arched steel frame. The sliding movable seat slides on the sliding track, and the limiting connecting members symmetrically arranged on the left and right sides of the upper end of the sliding movable seat slide with the limiting reinforcement members.

[0009] The rail clamping assembly is used to simultaneously clamp and fix the rail from the three sliding contact surfaces of the sliding movable seat and the sliding rail. When the rail clamping assembly releases the rail clamping fixation between the sliding movable seat and the sliding rail, the corresponding moving hydraulic cylinder drives the sliding movable seat to move forward along the sliding rail, thereby realizing the concrete pouring of the arch concrete pouring assembly onto the steel cage on the arch base.

[0010] Preferably, the arched steel frame includes a bottom beam fixed to the upper end of the hydraulic rail moving assembly, a side steel frame fixed to the upper end of the bottom beam, a top triangular steel frame fixed at equal intervals between the tops of the left and right side steel frames, and curved supports at equal intervals between the left and right bottom beams.

The front and rear ends of the upper part of the sliding base are fixedly connected to the other ends of the two sets of left and right limiting plates. The top of the protrusion is fixed to the bottom of the bottom beam.

[0017] The limiting connector includes a vertical frame symmetrically fixed to the upper end of the sliding movable seat and a rectangular frame fixed to the top of the vertical frame, the rectangular frame being sleeved on the corresponding limiting plate.

[0018] Preferably, the lower end of the sliding seat is provided with a sliding groove in the front-to-back direction, and the sliding track slides into the sliding groove;

[0019] The sliding movable seat is provided with two sets of front and rear side receiving grooves on both the left and right sides, and the bottom inner side of the side receiving groove is connected to the sliding groove.

[0022] The intermediate clamping member engages with the inner wall of the lifting square tube through a gear on the square tube;

[0023] The sliding rod fixed inside the side clamping member slides with the top side of the lifting square tube.

[0024] The clamping hydraulic cylinder is used to drive the side clamping parts on the left and right sides to close and clamp the sides of the sliding track. At the same time, the side clamping parts drive the lifting square tube to move down along the square tube through the sliding rod, so that the lifting square tube drives the middle clamping part to move down along the square tube through the gear until the bottom of the middle clamping part moves down along the middle receiving groove and clamps at the top of the sliding track.

[0025] Preferably, the side clamping component includes a side clamping head, a side rubber clamping block fixed to the bottom inner side of the side clamping head, and a connecting plate fixed to the inner top of the side clamping head, with a fixing rod connecting the front and rear connecting plates;

This allows for precise control of the moving distance. The clamping rail component simultaneously clamps and locks the three sliding contact surfaces, preventing trolley displacement and achieving precise alignment of the pouring position. This overcomes the shortcomings of traditional manual operation and simple auxiliary measures, which cannot achieve precise positioning. The linkage clamping design of the clamping rail component ensures a firm clamping action and convenient operation, effectively preventing unexpected trolley movement and slippage risks. Compared with traditional braking and limiting measures, the braking and fixing effects are superior, ensuring the safety of equipment and personnel during construction. Attached Figure Description

[0053] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0054] Example:

[0055] Please see Figures 1-18 The present invention provides a technical solution:

[0056] A large arched structure construction lining trolley includes an arched base 1, and arched concrete pouring components sliding on sliding rails 2 on the left and right sides of the upper end of the arched base 1. The arched concrete pouring components include an arched steel frame 5, an arched pouring steel template 8 fixed at the bottom of the middle of the arched steel frame 5, and a concrete pouring bucket 6 fixed at the front and rear of the top of the arched steel frame 5. The arched steel frame 5 includes a bottom beam 501 fixed to the upper end of a hydraulic rail moving component 7, side steel frames 502 fixed to the upper end of the bottom beam 501, a top triangular steel frame 505 fixed at equal intervals between the tops of the left and right side steel frames 502, and curved supports 503 arranged at equal intervals between the left and right bottom beams 501. The top of the curved support 503 is fixed to the bottom of the corresponding top triangular steel frame 505. The inner side of the top of the side steel frame 502 is provided with inclined supports 504 arranged at equal intervals, and the arched pouring steel template 8 is fixed to the bottom of the inclined supports 504.

[0057] The arched steel frame 5, as the core load-bearing structure of the casting component, adopts a modular design and consists of a bottom beam 501, side steel frames 502, curved supports 503, diagonal supports 504, and a top triangular steel frame 505. It has strong structural stability and high load-bearing capacity, and can adapt to the construction needs of large arched structures.

[0058] The bottom beam 501 is fixed to the upper end of the hydraulic rail moving assembly 7, providing stable support for the entire arched steel frame 5. The side steel frame 502 is fixed to the upper end of the bottom beam 501, and the top triangular steel frame 505 is fixed at equal intervals between the tops of the two sets of side steel frames 502, which can effectively disperse the vertical pressure of the arched structure. The curved support 503 is set at equal intervals between the two sets of bottom beams 501, and its top is fixed to the bottom of the corresponding top triangular steel frame 505, which further enhances the overall rigidity of the arched steel frame 5 and prevents it from deforming when bearing the weight of concrete. The inclined support 504 on the inner side of the top of the side steel frame 502 is set at equal intervals, and the arched casting steel formwork 8 is fixed to the bottom of the inclined support 504. The inclined support 504 can provide uniform support force for the arched casting steel formwork 8, ensuring the flatness and forming accuracy of the steel formwork, while avoiding local depressions and deformations of the steel formwork due to concrete pressure, thus ensuring the forming quality of the arched reinforced concrete 3.

[0059] The bottom of the concrete pouring hopper 6 is connected to the arched casting steel formwork 8 by a concrete conveying pipe 601. The arched casting steel formwork 8 covers the top of the reinforcing cage 4, and the inner wall of the bottom of the reinforcing cage 4 is also provided with an inner arc-shaped support plate 9. The lower ends of the left and right sides of the inner arc-shaped support plate 9 are fixed on the arch base 1. After the reinforcing cage 4 is filled with concrete, it forms reinforced concrete 3.

[0060] The bottom of the concrete pouring hopper 6 is connected to the arched steel formwork 8 via a concrete conveying pipe 601. This connection method enables precise concrete delivery, avoids spillage and waste during delivery, and ensures that the concrete is evenly filled to all parts of the arched steel formwork 8, reducing quality defects such as voids and honeycomb. The concrete pouring hopper 6 is set on the front and rear sides of the top of the arched steel frame 5, enabling multi-point synchronous material supply, improving concrete pouring efficiency, and adapting to the large-area pouring needs of large arched structures.

[0061] The lower ends of the inner arc-shaped support plate 9 on both sides are fixed to the arch base 1, and the top is attached to the inner wall of the steel cage 4. This allows for precise positioning and stable support of the steel cage 4, preventing deformation and displacement of the steel cage 4 due to concrete pressure during the pouring process. This ensures the bonding accuracy between the steel cage 4 and the concrete, thereby guaranteeing the structural strength and molding quality of the reinforced concrete 3. At the same time, this connection method is easy to install and disassemble, and can be adapted to the support requirements of steel cages 4 of different specifications.

[0062] Two sets of hydraulic rail clamping moving assemblies 7 are fixed to the lower ends of both sides of the arched steel frame 5. Each hydraulic rail clamping moving assembly 7 includes a sliding base 701, a sliding moving seat 704 connected to the front and rear ends of the bottom of the sliding base 701 by a moving hydraulic cylinder 703, and a rail clamping assembly mounted on the sliding moving seat 704. The pulleys 702 inside the sliding base 701 sit on the sliding rail 2. The upper front and rear ends of the sliding base 701 are provided with limiting reinforcements fixed to the lower end of the arched steel frame 5. The sliding moving seat 704 slides on the sliding rail 2. A front-to-back sliding groove 710 is provided in the middle of the lower end of the sliding moving seat 704, and the sliding rail 2 slides on the sliding groove 710. The hydraulic rail clamping moving... The sliding base 701 of the moving component 7 is fixed to the bottom of the bottom beam 501. The sliding base 701 is slidably connected to the sliding rail 2 via pulley 702. The sliding moving seat 704 is connected to the sliding base 701 via a moving hydraulic cylinder 703, and the sliding moving seat 704 is slidably connected to the sliding rail 2. This connection method realizes the flexible sliding connection between the arch concrete pouring component and the sliding rail 2. At the same time, the sliding moving seat 704 is driven to move by the moving hydraulic cylinder 703. The drive is smooth and the power is sufficient. It can accurately control the moving distance and speed of the arch concrete pouring component, ensure the accurate connection of each pouring position, avoid misalignment and deviation, and improve the overall lining construction accuracy.

[0063] Furthermore, the left and right symmetrically arranged limiting connectors and limiting reinforcements on the upper end of the sliding movable seat 704 are slidably connected; the sliding base 701 is fixed to the bottom of the bottom beam 501; the front and rear ends of the bottom of the sliding base 701 are movably connected to the moving hydraulic cylinder 703 by pins, and the first piston rod 706 at the output end of the moving hydraulic cylinder 703 is movably connected to the corresponding sliding movable seat 704 by pins; the limiting reinforcement includes two sets of left and right limiting plates 705 and protrusions 708 fixed at the ends of the two sets of left and right limiting plates 705, the front and rear ends of the upper part of the sliding base 701 are fixedly connected to the other ends of the two sets of left and right limiting plates 705, and the top of the protrusions 708 is fixed to the bottom of the bottom beam 501; the limiting connector includes a vertical frame 707 symmetrically fixed on the upper end of the sliding movable seat 704 and a rectangular frame 713 fixed at the top of the vertical frame 707, and the rectangular frame 713 is sleeved on the corresponding limiting plate 705.

[0064] The limiting reinforcement includes two sets of left and right limiting plates 705 and protrusions 708. The upper front and rear ends of the sliding base 701 are fixed to the limiting plates 705, and the top of the protrusions 708 is fixed to the bottom of the bottom beam 501, which can enhance the connection strength between the sliding base 701 and the bottom beam 501 and prevent the connection from loosening. The limiting connector includes a stand 707 and a rectangular frame 713. The stand 707 is fixed to the upper end of the sliding movable seat 704, and the rectangular frame 713 is sleeved on the limiting plate 705. This sliding connection method can accurately limit the movement direction of the sliding movable seat 704, ensuring that the sliding movable seat 704 always moves along the extension direction of the sliding track 2, avoiding deviation and tilting. At the same time, it can distribute the force on the sliding movable seat 704 and further improve the stability of the equipment during movement.

[0065] The rail clamping assembly is used to simultaneously clamp and fix the sliding contact surfaces of the sliding movable seat 704 and the sliding rail 2. The sliding movable seat 704 is provided with two sets of front and rear side receiving grooves 711 on both the left and right sides, and the bottom inner side of the side receiving groove 711 is connected to the sliding groove 710. The middle part of the sliding movable seat 704 is provided with a middle receiving groove 717, and the upper middle part of the sliding movable seat 704 is provided with a square tube 714, which is connected to the middle receiving groove 717.

[0066] The rail clamping assembly includes a side clamping member movably connected to the side receiving groove 711 by a pin 712, a clamping hydraulic cylinder 730 connected at the top between the left and right side clamping members, a middle clamping member sliding inside the square tube 714, and a lifting square tube fitting sleeved on the outside of the square tube 714; the middle clamping member engages with the inner wall of the lifting square tube fitting through a gear 718 on the square tube 714; the sliding rod 735 fixed inside the side clamping member slides with the top side of the lifting square tube fitting; the clamping hydraulic cylinder 730 is used to drive the left and right side clamping members to close and clamp both sides of the sliding rail 2, while the side clamping members drive the lifting square tube fitting to move down along the square tube 714 through the sliding rod 735, so that the lifting square tube fitting drives the middle clamping member to move down along the square tube 714 through the gear 718 until the bottom of the middle clamping member moves down along the middle receiving groove 717 and is clamped at the top of the sliding rail 2.

[0067] The side clamping component includes a side clamping head 709, a side rubber clamping block 734 fixed to the bottom inner side of the side clamping head 709, and a connecting plate 732 fixed to the inner top of the side clamping head 709. A fixing rod 733 is connected between the front and rear connecting plates 732. The clamping hydraulic cylinder 730 and the second piston rod 731 at the output end of the clamping hydraulic cylinder 730 are respectively movably connected to the corresponding fixing rod 733.

[0068] The intermediate clamping component includes an intermediate lifting seat 724 that slides inside the square tube 714, a lifting plate 728 that is fixed after the bottom of the intermediate lifting seat 724 extends into the intermediate receiving groove 717, and a top rubber clamping block 726 fixed at the lower end of the lifting plate 728. A first toothed groove 725 is provided in the first vertical inner groove 727 on the side of the intermediate lifting seat 724. The lifting square tube component includes an outer lifting square tube 719 that is sleeved on the outside of the square tube 714. A second toothed groove 720 is provided in the second vertical inner groove 721 on the inner wall of the outer lifting square tube 719. A gear 718 is movably connected to the reserved through groove 716 on the side of the square tube 714 by a gear shaft. The inner and outer sides of the gear 718 are respectively meshed with the corresponding first toothed groove 725 and second toothed groove 720.

[0069] The outer lifting square tube 719 has a bottom plate 723 at both the top and the front and rear ends, and the sliding rod 735 slides into the horizontal groove 722 in the bottom plate 723; the square tube 714 has a top plate 715 at both the top and the front and rear ends, and a return spring 729 is connected between the top plate 715 and the corresponding bottom plate 723.

[0070] The rail clamping assembly can simultaneously clamp and fix the rail from three sliding contact surfaces of the sliding movable seat 704 and the sliding rail 2. Compared with the traditional single-sided clamping, the fixing effect is more secure, which can effectively prevent relative sliding between the sliding movable seat 704 and the sliding rail 2 during the pouring process and ensure the pouring accuracy. The specific structural design benefits are as follows:

[0071] (1) Drive cooperation between side clamping parts and clamping hydraulic cylinder 730: The side clamping parts are movably connected to the side receiving groove 711 through the pin 712. The left and right side clamping parts are connected by the clamping hydraulic cylinder 730. The clamping hydraulic cylinder 730 drives the left and right side clamping parts to close through the second piston rod 731, which can quickly achieve clamping and fixing of both sides of the sliding rail 2. The operation is convenient and the clamping force is adjustable, which can meet the fixing requirements of different specifications of sliding rail 2. The side rubber clamping block 734 fixed inside the side clamping parts can increase the friction with the sliding rail 2, improve the clamping stability, and avoid mechanical damage to the sliding rail 2 during the clamping process.

[0072] (2) Interlocking of intermediate clamping component and lifting square tube component: The intermediate clamping component slides inside the square tube 714, and the lifting square tube component is sleeved on the outside of the square tube 714. The two are connected by gear 718. The side clamping component slides with the top side of the lifting square tube component through sliding rod 735. When the clamping hydraulic cylinder 730 drives the side clamping component to close, the side clamping component drives the lifting square tube component to move down along the square tube 714 through sliding rod 735. The lifting square tube component drives the intermediate clamping component to move down synchronously through gear 718 until the top rubber clamping block 726 at the bottom of the intermediate clamping component clamps the top of the sliding rail 2, realizing "synchronous linkage between side clamping and top clamping". There is no need to control the intermediate clamping component separately, which simplifies the operation process and improves the clamping and fixing efficiency. At the same time, the top rubber clamping block 726 can further improve the clamping stability and avoid slippage.

[0073] (3) Function of the reset spring 729: The reset spring 729 connected between the top plate 715 and the bottom plate 723 can drive the lifting square tube to automatically reset when the rail clamping assembly is released, thereby driving the middle clamping piece and the side clamping piece to reset, which facilitates the rapid movement of the equipment and improves construction efficiency.

[0074] The core principle of the rail clamping assembly for synchronously clamping and fixing the three sliding contact surfaces is "single drive source linkage multiple clamping components". The clamping hydraulic cylinder 730 is the only driving force. Through the mechanical linkage structure, it drives the side clamping component and the middle clamping component to move synchronously, respectively acting on the left and right sides and the top three sliding contact surfaces of the sliding moving seat 704 and the sliding rail 2, to achieve synchronous clamping and synchronous locking.

[0075] The specific working principle is broken down as follows: First, the three sliding contact surfaces of the sliding movable seat 704 and the sliding rail 2 are: the contact surfaces of the left and right side walls of the sliding groove 710 of the sliding movable seat 704 and the left and right side walls of the sliding rail 2, and the contact surface of the inner top surface of the sliding groove 710 and the top surface of the sliding rail 2. The side clamping parts of the rail clamping assembly act on the left and right side contact surfaces, and the middle clamping part acts on the top contact surface. The three parts achieve synchronous movement through the linkage structure.

[0076] When the arched concrete pouring assembly moves to the designated pouring position and needs to be locked, the clamping hydraulic cylinder 730 is activated. The second piston rod 731 at the output end of the clamping hydraulic cylinder 730 extends and pushes the bottom of the side clamping parts on the left and right sides to rotate inward around the pin 712. As the bottom of the side clamping parts rotates inward, the side rubber clamping blocks 734 fixed on their inner side gradually approach and fit against the left and right sides of the sliding track 2, and begin to apply clamping force to the sliding contact surfaces on the left and right sides.

[0077] At the same time, the top of the side clamping member drives the sliding rod 735 to rotate outward synchronously. The sliding rod 735 slides in the horizontal groove 722 of the top bottom plate 723 of the lifting square tube. The two sets of sliding rods 735 move away from each other along the horizontal groove 722, which will drive the outer lifting square tube 719 to slide smoothly upward along the square tube 714 (the square tube 714 is fixed in the middle of the upper end of the sliding moving seat 704, providing vertical guidance for the outer lifting square tube 719, ensuring that it can only move in the vertical direction and avoid deviation).

[0078] Because the second vertical inner groove 721 on the inner wall of the outer lifting square tube 719 is provided with a second tooth groove 720, and meshes with the outer side of the gear 718 in the reserved through groove 716 on the side of the square tube 714, and the inner side of the gear 718 meshes with the first tooth groove 725 of the first vertical inner groove 727 on the side of the middle clamping member (middle lifting seat 724), when the outer lifting square tube 719 slides upward, it will drive the gear 718 to rotate around the gear shaft through the second tooth groove 720, and the gear 718 will further drive the middle lifting seat 724 to slide downward synchronously along the square tube 714 through the first tooth groove 725;

[0079] The lifting plate 728 at the bottom of the intermediate lifting seat 724 moves downward, causing the top rubber clamping block 726 fixed at the lower end of the lifting plate 728 to move down along the intermediate receiving groove 717 until the top rubber clamping block 726 is tightly attached to the top surface of the sliding track 2, applying clamping force to the top sliding contact surface.

[0080] When the second piston rod 731 of the clamping hydraulic cylinder 730 extends to the preset stroke, the clamping force of the side rubber clamping block 734 on the left and right sides of the sliding rail 2 and the top rubber clamping block 726 on the top surface of the sliding rail 2 reaches the preset value. The synchronous clamping action of the three sliding contact surfaces is completed, realizing the firm locking of the sliding moving seat 704 and the sliding rail 2. At this time, the position of the arched concrete pouring component is fixed, and concrete pouring operation can be carried out safely.

[0081] Throughout the process, the three contact surfaces can be clamped synchronously by driving only one clamping hydraulic cylinder 730. There is no need to control each clamping component separately, which ensures the coordination and synchronicity of the clamping action and avoids equipment displacement problems caused by weak clamping on a single contact surface or uneven force.

[0082] When the rail clamping assembly releases the sliding movable seat 704 from the sliding rail 2, the corresponding moving hydraulic cylinder 703 drives the sliding movable seat 704 to move forward along the sliding rail 2, thereby realizing the concrete pouring of the arch concrete pouring assembly onto the steel cage 4 on the arch base 1.

[0083] Specifically, when using it:

[0084] The core working principle of this large arch structure construction lining trolley is to achieve precise and efficient pouring of arch reinforced concrete 3 through modular structural combination. The overall workflow revolves around four major stages: "positioning-supporting-pouring-moving," with each structure working in concert, as detailed below:

[0085] 1. Initial positioning of the equipment: Fix the arch base 1 at the construction reference position as the load-bearing foundation of the entire trolley to ensure the overall stability of the equipment; at the same time, place the steel cage 4 at the preset position of the arch base 1, and use the inner arc support plate 9 to limit and support the steel cage 4. The lower ends of the left and right sides of the inner arc support plate 9 are fixed on the arch base 1, and its arc structure fits against the inner wall of the steel cage 4, which can prevent the steel cage 4 from deforming or shifting during the pouring process, and provide a precise forming reference for subsequent concrete pouring.

[0086] 2. Positioning of the pouring assembly: The arched concrete pouring assembly is driven by the hydraulic rail clamping moving assembly 7 to slide along the sliding rail 2 until the arched pouring steel formwork 8 is precisely placed on top of the reinforcing cage 4. After the arched pouring steel formwork 8 is in place, the rail clamping assembly is activated to synchronously clamp and fix the three sliding contact surfaces of the sliding moving seat 704 and the sliding rail 2, locking the position of the arched concrete pouring assembly to prevent displacement during pouring and ensure pouring accuracy.

[0087] 3. Concrete pouring operation: Concrete is poured into the concrete hopper 6 fixed at the front and back of the top of the arched steel frame 5. The concrete is then precisely delivered to the inside of the arched casting steel formwork 8 through the concrete delivery pipe 601 at the bottom of the concrete hopper 6. The arched casting steel formwork 8 serves as the molding mold for the concrete. Its shape matches the arched structure to be formed and it is fixed at the bottom of the inclined support 504, which can ensure that the concrete is evenly distributed and densely filled inside the reinforcing cage 4. During the pouring process, the reinforcing cage 4 combines with the poured concrete to finally form the reinforced concrete 3 that meets the design requirements.

[0088] 4. Equipment movement and continuous construction: After the concrete pouring of a section of steel cage 4 is completed, the fixed state of the rail clamping assembly on the front sliding moving seat 704 is released, and the moving hydraulic cylinder 703 is started. The rear moving hydraulic cylinder 703 drives the sliding base 701 to move forward along the sliding track 2 through the extension of the first piston rod 706; at the same time, the first piston rod 706 of the front moving hydraulic cylinder 703 retracts.

[0089] Then, the rail clamping assembly on the front sliding movable seat 704 clamps the sliding rail 2, releasing the fixed state of the rail clamping assembly on the rear sliding movable seat 704.

[0090] When the movable hydraulic cylinder 703 is activated, the front movable hydraulic cylinder 703 drives the sliding base 701 to move forward along the sliding track 2 through the extension of the first piston rod 706; at the same time, the first piston rod 706 of the rear movable hydraulic cylinder 703 retracts.

[0091] By operating in the above sequence, the entire arched concrete pouring assembly is moved synchronously. After reaching the pouring position of the next section of the steel cage 4, the rail clamping assembly is locked again, and the above pouring process is repeated to achieve continuous and efficient lining construction of large arched structures.

[0092] Although embodiments of the 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 these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
